I. This prophet here repeats the heads of the sermons which the former prophets preached to their fathers (v. 9, 10), because the very same things were required of them now. "Thus does the Lord of hosts speak to you now, and thus he did speak to your fathers, saying, Execute true judgment." The duties here required of them, which would have been the lengthening of the tranquillity of their fathers and must be the restoring of their tranquillity, are not keeping fasts and offering sacrifices, but doing justly and loving mercy, duties which they were bound to by the light and law of nature, though there had been no prophets sent to insist upon them, duties which had a direct tendency to the public welfare and peace, and which they themselves would be the gainers by, and not God. 1. Magistrates must administer justice impartially, according to the maxims of the law and the merits of the cause, without respect of persons: "Judge judgment of truth, and execute it when you have judged it." 2. Neighbours must have a tender concern for one another, and must not only do one another no wrong, but must be ready to do one another all the good offices that lie in their power. They must show mercy and compassion every man to his brother, as the case called for it. The infirmities of others, as well as their calamities, are to be looked upon with compassion. Hanc veniam petimusque damusque vicissim—This kindness we ask and exercise. 3. They must not bear hard upon those whom they have advantage against, and who, they know, are not able to help themselves. They must not, either in commerce or in course of law, oppress the widow, the fatherless, the stranger, and the poor, v. 10. The weakest must not be thrust to the wall because they are weakest. No thanks to men not to deny right to those who are in a capacity to demand it and recover it; but we must, not only for wrath, but also for conscience' sake, give those their own who have not power to force it from us. Or it intimates that that which is but exactness with others is exaction upon the widows and the fatherless; nay, that not relieving and helping them as we ought is, in effect, oppressing them. 4. They must not only not do wrong to any, but they must not so much as desire it nor think of it: "Let none of you imagine evil against his brother in your heart. Do not project it; do not wish it; nay do not so much as please yourself with the fancy of it." The law of God lays a restraint upon the heart, and forbids the entertaining, forbids the admitting, of a malicious, spiteful, ill-natured thought. Deut. xv. 9, Beware that there be not a thought in thy Belial heart against thy brother.
