Therefore, if thou shalt bring thy gift This clause confirms, and at the same time explains, the preceding doctrine. It amounts to this, that the precept of the law, which forbids murder, (Exodus 20:13,) is obeyed, when we maintain agreement and brotherly kindness, with our neighbor. To impress this more strongly upon us, Christ declares, that even the duties of religion are displeasing to God, and are rejected by him, if we are at variance with each other. When he commands those who have injured any of their brethren, to be reconciled to him, before they offer their gift, his meaning is, that, so long as a difference with our neighbor is kept up by our fault, we have no access to God. But if the worship, which men render to God, is polluted and corrupted by their resentments, this enables us to conclude, in what estimation he holds mutual agreement among ourselves. Here a question may be put. Is it not absurd, that the duties of charity should be esteemed more highly than the worship of God? We shall then be forced to say, that the order of the law is improper, or that the first table of the law must be preferred to the second. The answer is easy: for the words of Christ mean nothing more than this, that it is a false and empty profession of worshipping God, which is made by those who, after acting unjustly towards their brethren, treat them with haughty disdain. By a synecdoche he takes a single class to express the outward exercises of divine worship, which in many men are rather the pretenses, than the true expressions, of godliness. It ought to be observed that Christ, adapting his discourse to that age, speaks of sacrifices. Our condition is now different: but the doctrine remains the same, that whatever we offer to God is polluted, unless, at least as much as lieth in us, (Romans 12:18,) we are at peace with our brethren. Alms are called in Scripture sacrifices of a sweet smell, (Philippians 4:18;) and we learn from the mouth of Paul, that he who "spends all his substance on the poor, if he have not charity, is nothing," (1-Corinthians 13:3.) Lastly, God does not receive and acknowledge, as his sons, any who do not, in their turn, show themselves to be brethren to each other. Although it is only to those who have injured their brethren that these words are addressed, enjoining them to do their endeavor to be reconciled to them, yet under one class he points out, how highly the harmony of brethren is esteemed by God. When he commands them to leave the gift before the altar, he expresses much more than if he had said, that it is to no purpose for men to go to the temple, or offer sacrifices to God, so long as they live in discord with their neighbors.

Therefore, if thou bring thy gift to the altar - The Pharisees were intent only on the external act in worship. They looked not at all to the internal state of the mind. If a man conformed to the external rites of religion, however much envy, and malice, and secret hatred he might have, they thought he was doing well. Our Saviour taught a different doctrine. It was of more consequence to have the heart right than to perform the outward act. If, therefore, says he, a man has gone so far as to bring his gift to the very altar, and should remember that anyone had anything against him, it was his duty there to leave his offering and go and be reconciled. While a difference of this nature existed, his offering could not be acceptable. He was not to wait until the offended brother should come to him; he was to go and seek him out, and be reconciled. So now the worship of God will not be acceptable, however well performed externally, until we are at peace with those that we have injured. "To obey is better than sacrifice," 1-Samuel 15:22. He that comes to worship his Maker filled with malice, and hatred, and envy, and at war with his brethren, is a hypocritical worshipper, and must meet with God's displeasure. God is not deceived, and he will not be mocked.
Thy gift - Thy sacrifice. What thou art about to devote to God as an offering.
To the altar - The altar was situated in front of the temple, and was the place on which sacrifices were made. See the notes on plan, Matthew 21:12. To bring a gift to the altar was expressive of worshipping God, for this was the way in which he was formerly worshipped.
Thy brother - Any man, especially any fellow-worshipper. Anyone of the same religious society.
Hath aught - Is offended, or thinks he has been injured by you in any manner.
First be reconciled - This means to settle the difficulty; to make proper acknowledgment or satisfaction for the injury. If you have wronged him, make restitution. If you owe him a debt which ought to be paid, pay it. If you have injured his character, confess it and seek pardon. If he is under an erroneous impression, if your conduct has been such as to lead him to suspect that you have injured him, make an explanation. Do all in your power; and all you ought to do, to have the matter settled. From this we learn:
1. That, in order to worship God acceptably, we must do justice to our fellow-men.
2. Our worship will not be acceptable unless we do all we can to live peaceably with others.
3. It is our duty to seek reconciliation with others when we have injured them.
4. This should be done before we attempt to worship God.
5. This is often the reason why God does not accept our offerings, and we go empty away from our devotions. We do not do what we ought to others; we cherish improper feelings or refuse to make proper acknowledgments, and God will not accept such attempts to worship him.

Therefore if thou bring thy gift - Evil must be nipped in the bud. An unkind thought of another may be the foundation of that which leads to actual murder. A Christian, properly speaking, cannot be an enemy to any man; nor is he to consider any man his enemy, without the fullest evidence: for surmises to the prejudice of another can never rest in the bosom of him who has the love of God in his heart, for to him all men are brethren. He sees all men as children of God, and members of Christ, or at least capable of becoming such. If a tender forgiving spirit was required, even in a Jew, when he approached God's altar with a bullock or a lamb, how much more necessary is this in a man who professes to be a follower of the Lamb of God; especially when he receives the symbols of that Sacrifice which was offered for the life of the world, in what is commonly called the sacrament of the Lord's supper!

(6) Therefore if thou bring thy gift to the (o) altar, and there rememberest that thy brother hath ought against thee;
(6) The covetous Pharisees taught that God was appeased by the sacrifices appointed in the law, which they themselves devoured. But Christ on the contrary side denies that God accepts any man's offering, unless he makes satisfaction to his brother whom he has offended: and says moreover, that these stubborn and stiff-necked despisers of their brethren will never escape the wrath and curse of God before they have made full satisfaction to their brethren.
(o) He applies all this speech to the state of his time, when there was then an altar standing in Jerusalem, and therefore they are very foolish that gather from this that we must build altars and use sacrifices: but they are bigger fools who consider this to be purgatory, which is spoken of as peace making and atonement one with another.

Therefore, if thou bring thy gift to the altar,.... The Jews obliged such who had done any damage to their neighbours, by stealing from them, to make satisfaction before they brought their offering; concerning which they say (c),
"he that brings what he has stolen, before he brings his trespass offering, is right; he that brings his trespass offering, before he brings that which he has stolen, is not right.''
Again (d),
"they do not bring the trespass offering before the sum of what is stolen is returned, either to the owners, or to the priests.''
Some have thought Christ refers to this; only what they restrained to pecuniary damages, he extends to all sorts of offences. But not a trespass offering, but a freewill offering, seems to be designed by "the gift": which, when a man either intended to bring, or was going to bring, or had already brought, as a voluntary sacrifice to be offered unto God; and it came into his mind, that he had offended any man by showing any undue passion, or by any reproachful words, then he was to do what is advised in the following verse: "and there", whilst going, or when at the altar,
rememberest that thy brother hath ought against thee: hath anything to charge thee with; any just ground of complaint against thee; if thou hast done him any injury, or given him any offence: particularly, if he had at any time said Raca to him, or called him "fool" for those words have reference to what goes before, and are a corollary, or conclusion from them, as appears from the causal particle "therefore".
(c) Misn. Bava Kama, c. 9. sect. 12. (d) Maimon. Hilch. Gezela, c. 8. sect. 13.

Therefore--to apply the foregoing, and show its paramount importance.
if thou bring thy gift to the altar, and there rememberest that thy brother hath aught--of just complaint "against thee."

Therefore, if thou bring thy gift to the altar. This springs immediately out of the modification of the law, Thou shalt not kill, which required that there should be no anger with a brother. If about to offer a gift on the altar, and the remembrance comes that a brother hath aught against thee, leave the gift, go and make it right with him, and then offer thy gift. This shows that one guilty of wrongs to his fellow-man cannot offer acceptable worship of God.

Thy brother hath aught against thee - On any of the preceding accounts: for any unkind thought or word: any that did not spring from love.
