Remember not former things. Hitherto the Prophet shewed how great was the power of God in delivering the people. He now declares that all the miracles which God wrought in that first redemption were of little importance as compared with the more remarkable miracle which should soon be wrought; that is, that the glory of this second deliverance shall be so great as to throw the former into the shade. Yet he does not mean that the Jews should forget so great a benefit, which he had commanded them to publish in every age, and to inscribe on permanent records; for in his preface to the Law he begins in this manner, "I am the Lord thy God, who brought thee out of the land of Egypt, out of the house of bondage." (Exodus 20:2.) He even enjoined parents to repeat it frequently to their children, and from hand to hand to deliver it to their grandchildren and to posterity. This must therefore be understood to be by comparison, like that saying' of Jeremiah, "Behold the days come," saith the Lord, "that it shall no longer be said, The Lord liveth, who brought the children of Israel out of the land of Egypt; but, The Lord liveth, who led and brought out the seed of the house of Israel from the land of the north, and from all the countries into which I had driven them; and they shall dwell in their land." (Jeremiah 23:7, 8.) In short, he shews that this latter redemption, when compared with the former, shall be far more illustrious. Hence it follows, that it is improper to limit this prediction to a small number of years; for the Prophet does not separate between its commencement and its progress, but extends the blessed consequences of their return till Christ, who, by his coming, actually set up the priesthood and the kingdom.

Remember ye not - So great and wonderful shall be God's future interpositions in your behalf, that what he has done, great as that was, shall be comparatively forgotten.
The former things - The deliverance from Egypt, and the overthrow of his enemies there.
The things of old - The things that were formerly done.

Remember ye not the former things,.... Just now referred to, the bringing of Israel out of Egypt, and through the Red sea, and the drowning of Pharaoh and his army in it; for though these things were worthy to be remembered with thankfulness and praise, and to the glory of God, and for the encouragement of faith, yet not in comparison of what was hereafter to be done; meaning, not the redemption from Babylon, unless as a type of spiritual and eternal redemption by Christ; for otherwise there were greater and more wonderful things done, when Israel were brought out of Egypt, than when they were brought out of Babylon; but the great salvation by the Messiah, which exceeds both the deliverances out of Egypt and Babylon, is meant:
neither consider the things of old; unless as figures of the new, but not to be put upon a foot with them, much less to the undervaluing of them, and indeed to be forgotten in comparison of them; see Jeremiah 23:7. The Talmudists (q), by the "former" things, understand subjection to kingdoms; and, by the "things of old", the going out of Egypt; as they do by the "new thing", in the following verse, the war of Gog and Magog.
(q) T. Bab. Beracot, fol. 13. 1. T. Hieros. Beracot, fol. 4. 1.

So wonderful shall be God's future interpositions in your behalf, that all past ones shall be forgotten in comparison. Plainly the future restoration of Israel is the event ultimately meant. Thus the "former things" are such events as the destruction of Sennacherib and the return from Babylon. "Things of old" are events still more ancient, the deliverance from Egypt and at the Red Sea, and entry into Canaan [VITRINGA].

Remember not - Tho' your former deliverance out of Egypt was glorious: yet in comparison of that inestimable mercy of sending the Messiah, all your former deliverances are scarce worthy of your remembrance and consideration.
