2. Let them do the duty which those promises call for from them, v. 16, 17. The very same duties which the former prophets pressed upon their fathers from the consideration of the wrath threatened (ch. vii. 9, 10) this prophet presses upon them from the consideration of the mercy promised: "Leave it to God, to perform for you what he has promised, in his own way and time, but upon condition that you make conscience of your duty. These are the things then that you shall do; this is your part of the covenant; these are the articles which you are to perform, fulfil, and keep, that you may not put a bar in your own door and stop the current of God's favours." (1.) "You must never tell a lie, but always speak as you think, and as the matter is, to the best of your knowledge: Speak you every man the truth to his neighbour, both in bargains and in common converse; dread every word that looks like a lie." This precept the apostle quotes (Eph. iv. 25), and backs it with this reason, We are members one of another. (2.) Those that are entrusted with the administration of public justice must see to it, not only that none be wronged by it, but that those who are wronged be righted by it: Execute the judgment of truth and peace in your gates. Let the judges that sit in the gates in all their judicial proceedings have regard both to truth and to peace; let them take care to do justice, to accommodate differences, and to prevent vexatious suits. It must be a judgment of truth in order to peace, and making those friends that were at variance, and a judgment of peace as far as is consistent with truth, and no further. (3.) No man must bear malice against his neighbour upon any account; this is the same with what we had ch. vii. 10. We must not only keep our hands from doing evil, but we must watch over our hearts, that they imagine not any evil against our neighbour, Prov. iii. 29. Injury and mischief must be crushed in the thought, in the embryo. (4.) Great reverence must be had for an oath, and conscience made of it: "Never take a false oath, nay, love no false oath; that is, hate it, dread it, keep at a distance from it. Love not to impose oaths upon others, lest they swear falsely; love not that any should take a false oath for your benefit, and forswear themselves to do you a kindness." A very good reason is annexed against all these corrupt and wicked practices: "For all these are things that I hate, and therefore you must hate them if you expect to have God your friend." These things here forbidden are all of them found among the seven things which the Lord hates, Prov. vi. 16-19. Note, We must forbear sin, not only because God is angry at it, and therefore it is dangerous to us, but because he hates it, and therefore it ill becomes us and is a very ungrateful thing.
