IV. Here is a believing appeal to the mercy of God, and to the ancient tokens of his favour to Israel, and the concern of his own glory in their interests. 1. It is some comfort to them (and not a little) that God has been always ready to pardon sin (v. 9): To the Lord our God belong mercies and forgiveness; this refers to that proclamation of his name, Exod. xxxiv. 6, 7, The Lord God, gracious and merciful, forgiving iniquity. Note, It is very encouraging to poor sinners to recollect that mercies belong to God, as it is convincing and humbling to them to recollect that righteousness belongs to him; and those who give him the glory of his righteousness may take to themselves the comfort of his mercies, Ps. lxii. 12. There are abundant mercies in God, and not only forgiveness but forgivenesses; he is a God of pardons (Neh. ix. 17, marg.); he multiplies to pardon, Isa. lv. 7. Though we have rebelled against him, yet with him there is mercy, pardoning mercy, even for the rebellious. 2. It is likewise a support to them to think that God had formerly glorified himself by delivering them out of Egypt; so far he looks back for the encouragement of his faith (v. 15): "Thou hast formerly brought thy people out of Egypt with a mighty hand, and wilt thou not now with the same mighty hand bring them out of Babylon? Were they then formed into a people, and shall they not now be reformed and new-formed? Are they now sinful and unworthy, and were they not so then? Are their oppressors now mighty and haughty, and were they not so then? And has not God said that their deliverance out of Babylon shall outshine even that out of Egypt?" Jer. xvi. 14, 15. The force of this plea lies in that, "Thou hast gotten thyself renown, hast made thyself a name" (so the word is) "as at this day, even to this day, by bringing us out of Egypt; and wilt thou lose the credit of that by letting us perish in Babylon? Didst thou get a renown by that deliverance which we have so often commemorated, and wilt thou not now get thyself a renown by this which we have so often prayed for, and so long waited for?"
