Salt and Light
13 You are the salt of the earth, but if salt has lost its taste, how shall its saltiness be restored? It is no longer good for anything except to be thrown out and trampled under people’s feet.
John Gill
You are the salt of the earth—This is to be understood of the disciples and apostles of Christ; who might be compared to “salt,” because of the savoury doctrines they preached; as all such are, which are agreeable to the Scriptures, and are of the evangelic kind, which are full of Christ, serve to exalt him, and to magnify the grace of God; and are suitable to the experiences of the saints, and are according to godliness, and tend to promote it: also because of their savoury lives and conversations; whereby they recommended, and gave sanction to the doctrines they preached, were examples to the saints, and checks upon wicked men. These were the salt “of the earth”; that is, of the inhabitants of the earth, not of the land of Judea only, where they first lived and preached, but of the whole world, into which they were afterwards sent to preach the gospel.
But if salt has lost its taste, how shall its saltiness be restored? The “taste” here supposed that it may be lost, cannot mean the taste of grace, or true grace itself, which cannot be lost, being an incorruptible seed; but either gifts qualifying men for the ministry, which may cease; or the savoury doctrines of the gospel, which may be departed from; or a seeming savoury conversation, which may be neglected; or that seeming taste, zeal, and affection, with which the gospel is preached, which may be dropped: and particular respect seems to be had to Judas, whom Christ had chosen to the apostleship, and was a devil; and who he knew would lose his usefulness and place, and become an unprofitable wretch, and at last be rejected of God and men; and this case is proposed to them all, in order to engage them to take heed to themselves, their doctrine and ministry. Moreover, this is but a supposition;
If salt—And proves no matter of fact; and the Jews have a saying, that all that season lose their taste, “but salt does not lose its taste.” Should it do so,
It is no longer good for anything except to be thrown out and trampled under people’s feet—Salt is no longer good for anything except to make things savoury, and preserve from putrefacation; and when it has lost its taste, it is of no use, neither to men nor beasts, as some things are when corrupted; nor is it of any use to the land, or dunghill, for it makes barren, and not fruitful: so ministers of the word, when they have dropped the savoury doctrines of the gospel, or have quitted their former seeming savoury and exemplary conversations; as their usefulness is gone, so, generally speaking, it is never retrieved; they are cast out of the churches of Christ, and are treated with contempt by everyone.
You shall season all your grain offerings with salt. You shall not let the salt of the covenant with your God be missing from your grain offering; with all your offerings you shall offer salt. LEV 2:13
Berakhot 5a:19
And that is the statement of Rabbi Shimon ben Lakish, as Rabbi Shimon ben Lakish said: The word covenant is used with regard to salt, and theword covenant is used with regard to afflictions. The word covenant is used with regard to salt, as it is written: “The salt of the covenant with your God should not be excluded from your grain offering; with all your sacrifices you shall offer salt” (Lev 2:13). And the word covenant is used with regard to afflictions, as it is written: “These are the words of the covenant” (Deu 28:69). Just as, in the covenant mentioned with regard to salt, the salt sweetens the taste of the meat and renders it edible, so too in the covenant mentioned with regard to suffering, the suffering cleanses a person’s transgressions, purifying him for a more sublime existence.
John Gill
You shall season all your grain offerings with salt—Which makes food savoury, and preserves from putrefaction; denoting the savouriness and acceptableness of Christ as a grain offering to his people, he being savoury food, such as their souls love, as well as to God the Father, who is well pleased with his sacrifice; and also the perpetuity of his sacrifice, which always has the same virtue in it, and of him as a grain offering, who is that meat which endures to everlasting life (Joh 6:27), and also the grave and gracious conversation of those that by faith feed upon him (Mar 9:50; Col 4:6),
You shall not let the salt of the covenant with your God be missing from your grain offering—This seems to suggest the reason why salt was used in grain offerings, and in all others, because it was a symbol of the perpetuity of the covenant, which from thence is called a covenant of salt (Num 18:19), namely, the covenant of the priesthood, to which these sacrifices belonged (Num 25:13), hence the Targum of Jonathan,
“because the twenty four gifts of the priests are decreed by the covenant of salt, therefore upon all your offerings you shall offer salt”:
With all your offerings you shall offer salt—Even those that were not to be eaten, as well as those that were; as the burnt offering of the herd, of the flock, and of fowls, and their several parts; all were obliged to be salted that were offered, excepting wine, blood, wood, and incense; hence there was a room in the temple where salt was laid up for this purpose, called “the salt room”; and which was provided by the congregation, and not by a private person; our Lord has reference to this law in Mar 9:49 the Gentiles always made use of salt in their sacrifices.
Rashi
The salt of the covenant with your God, because a covenant was established with the salt as far back as the six days of creation when the lower waters received an assurance that they would be offered on the altar in the form of salt and also as water in the ceremony of “the libation of water” on the Feast of Booths.
With all your offerings you shall offer salt—Upon burnt offerings of cattle and fowls and upon the fat portions of all sacrifices in general (Menachot 20a).
14 You are the light of the world. A city set on a hill cannot be hidden.
But the path of the righteous is like the light of dawn,
which shines brighter and brighter until full day. PRO 4:18
Rashi
But the path of the righteous is like the light of dawn which shines and illuminates from the first ray of dawn.
Until full day—Until midday, which is the brightest time of day.
15 Nor do people light a lamp and put it under a basket, but on a stand, and it gives light to all in the house.
16 In the same way, let your light shine before others, so that they may see your good works and give glory to your Father who is in heaven.
John Gill
Let your light shine before others—Here Christ applies the foregoing simile to his disciples, and more fully opens the meaning and design of it. His sense is this; that the light of the gospel, which he had communicated to them, the spiritual knowledge of the mysteries of grace, which he had favoured them with, were to be openly declared, and made manifest before men. Light was not given merely for their own private use, but for the public good of mankind; and therefore, as they were placed as lights in the world, they were to hold forth, in the most open and conspicuous manner, the word of light and life:
That they may see your good works—Meaning their zeal and fervency; their plainness and openness; their sincerity, faithfulness, and integrity; their courage and intrepidity; their diligence, industry, and indefatigableness in preaching the gospel; their strict regard to truth, the honour of Christ, and the good of souls; as also their very great care and concern to recommend the doctrines of grace, by their example in their lives and conversations:
And give glory to your Father who is in heaven—That is, that when the ministration of the gospel has been blessed, for the illumination of the minds of men, to a thorough conviction of their state; and for their regeneration, conversion, sanctification, and comfort; they may give praise to God, and bless his name for qualifying and sending such gospel ministers to show to them the way of salvation; and that the word has been made useful to them for communicating spiritual light, life, joy, and comfort, “Our and your Father who is in heaven,” is a name, appellation, or periphrasis of God, frequently used by Jewish writers; and is often expressed by Christ in these his sermons on the mount.
Then shall your light break forth like the dawn,
and your healing shall spring up speedily;
your righteousness shall go before you;
the glory of the Lord shall be your rear guard. ISA 58:8
John Gill
Then shall your light break forth like the dawn—Through thick clouds, or the darkness of the night, suddenly, swiftly, irresistibly, and increase more and more, till it is perfect day. This is to be understood best of temporal and spiritual prosperity, especially the latter, which will attend the churches of the Reformation, when a spirit of persecution is laid aside, and a spirit of love commences, which will be in the Philadelphian church state; and it particularly respects the glorious light of the gospel, which will break forth very clearly, and shine out in all the world; and the light of joy, peace, and comfort, which will attend it, in the hearts of the Lord’s people; see Isa 60:1:
And your healing shall spring up speedily—As the herbs and grass out of the earth, by clear shining after rain; by which is meant the healthful and sound state of the church in the latter day, when all divisions shall be healed; contentions and animosities cease; sound doctrine preached; the ordinances administered according to their original institution; true discipline restored; and all the parts of worship performed, according to the rule of the divine word; and so the souls of men, under all these means, be in thriving and flourishing circumstances:
Your righteousness shall go before you—Not the external righteousness of the saints, or works of righteousness done by them; these do not go before them, at least to prepare the way for them into a future state of happiness, but follow after (Rev 14:13), rather the righteousness of Christ imputed to them, and so theirs; or Christ their righteousness, the sun of righteousness, that arises upon them with healing in his wings, and from whom they have the health before mentioned; he goes before his people by way of example, as a guide to direct them, and as the forerunner of them, and whose righteousness will introduce them into the heavenly glory. Though perhaps the meaning here is, that their righteousness, in the latter day glory, shall be very manifest, both their righteousness before God, and before men; which will, as it were, visibly walk before them, make way for them, and protect them; see Isa 60:21,
And the glory of the Lord shall be your reward—The glorious power and providence of God, preserving his people; or the glorious Lord himself, our Lord Jesus Christ, the brightness of his Father’s glory, he, as the word may be rendered, “shall gather you”; are straggling behind; and he brings them up, being the reward, and saves them. The phrase denotes a glorious state of the church in the latter day, when the glory of the Lord will be risen on his church, and abide upon it, and upon all that glory there shall be a defence; see Isa 4:5; 60:1.
