2. Promising words. These also are put into their mouths, not to move God, or to oblige him to show them mercy, but to move themselves, and oblige themselves to returns of duty. Note, Our prayers for pardon and acceptance with God should be always accompanied with sincere purposes and vows of new obedience. Two things they are to promise and vow:—(1.) Thanksgiving. "Pardon our sins, and accept of us, so will we render the calves of our lips." The fruit of our lips (so the LXX.), a word they used for burnt-offerings, and so it agrees with the Hebrew. The apostle quotes this phrase (Heb. xiii. 15), and by the fruit of our lips understands the sacrifice of praise to God, giving thanks to his name. Note, Praise and thanksgiving are our spiritual sacrifice, and, if they come from an upright heart, shall please the Lord better than an ox or bullock, Ps. lxxix. 30, 32. And the sense of our pardon and acceptance with God will enlarge our hearts in praise and thankfulness. Those that are received graciously may, and must, render the calves of their lips—poor returns for rich receivings, yet, if sincere, more acceptable than the calves of the stall. (2.) Amendment of life. They are taught to promise, not only verbal acknowledgements, but a real reformation. And we are taught here, [1.] In our returns to God to covenant against sin. We cannot expect that God should take it away by forgiving it if we do not put it away by forsaking it. [2.] To be particular in our covenants and resolutions against sin, as we ought to be in our confession, because deceit lies in generals. [3.] To covenant especially and expressly against those sins which we have been most subject to, which have most easily beset us, and which we have been most frequently overcome by. We must keep ourselves from, and therefore must thus fortify ourselves against, our own iniquity, Ps. xviii. 23. The sin they here covenant against, owning thereby that they had been guilty of it, is giving that glory to another which is due to God only; this they promise they will never do, First, By putting that confidence in creatures which should be put in God only. They will not trust to their alliances abroad: Asshur (that is, Assyria) shall not save us. "We will not court the help of the Assyrians when we are in distress, as we have done (ch. v. 13; vii. 11; viii. 9); we will not contract for it, nor will we confide in it, or depend upon it. Having a God to go to, a God all-sufficient to trust to, we scorn to be beholden to the Assyrians for help." They will not trust to their warlike preparations at home, especially not those which they were forbidden to multiply: "We will not ride upon horses, that is, we will not make court to Egypt," for thence they fetched their horses, Deut. xvii. 16; Isa. xxx. 16; xxxi. 1, 3. "When our enemies invade us we will depend upon our God to succour our infantry, and will be in no care to remount our cavalry." Or, "We will not post on horseback, for haste, from one creature to another, to seek relief, but will take the nearest way, and the only sure way, by addressing ourselves to God," Isa. xx. 5. Note, True repentance takes us off from trusting to an arm of flesh, and brings us to rely on God only for all the good we stand in need of. Secondly, Nor will they do it by paying that homage to creatures which is due to God only. We will not say any more to the works of our hands, You are our gods. They must promise never to worship idols again, and for a good reason, because it is the most absurd and senseless thing in the world to pray to that as a god which is the work of our hands. We must promise that we will not set our hearts upon the gains of this world, nor pride ourselves in our external performances in religion, for that is, in effect, to say to the work of our hands, You are our gods.
