(1.) This may be understood either of the people or of God. [1.] We may understand it of the people. Israel then (spoken of as a single person) remembered the days of old, looked into their Bibles, read the story of God's bringing their fathers out of Egypt, considered it more closely than ever they did before, and reasoned upon it, as Gideon did (Judg. vi. 13), Where are all the wonders that our fathers told us of? "Where is he that brought them up out of Egypt? Is he not as able to bring us up out of Babylon? Where is the Lord God of Elijah? Where is the Lord God of our fathers?" This they consider as an inducement and an encouragement to them to repent and return to him; their fathers were a provoking people and yet found him a pardoning God; and why may not they find him so if they return to him? They also use it as a plea with God in prayer for the turning again of their captivity, like that ch. li. 9, 10. Note, When the present days are dark and cloudy it is good to remember the days of old, to recollect our own and others' experiences of the divine power and goodness and make use of them, to look back upon the years of the right hand of the Most High (Ps. lxxvii. 5, 10), and remember that he is God, and changes not. [2.] We may understand it of God; he put himself in mind of the days of old, of his covenant with Abraham (Lev. xxvi. 42); he said, Where is he that brought Israel up out of the sea? stirring up himself to come and save them with this consideration, "Why should not I appear for them now as I did for their fathers, who were as undeserving, as ill-deserving, as they are?" See how far off divine mercy will go, how far back it will look, to find out a reason for doing good to his people, when no present considerations appear but what make against them. Nay, it makes that a reason for relieving them which might have been used as a reason for abandoning them. He might have said, "I have delivered them formerly, but they have again brought trouble upon themselves (Prov. xix. 19); there I will deliver them no more," Judg. x. 13. But no; mercy rejoices against judgment, and turns the argument the other way: "I have formerly delivered them and therefore will now."
