(60) I will remember my covenant.--The remembrance of God's covenant is made the basis of His mercy to His penitent people (Leviticus 26:42-45) from the beginning, and it is often spoken of as an everlasting covenant. In the New Testament (Luke 1:54-55; Luke 1:72-73, &c.) this covenant is regarded as fulfilled in the Christian dispensation. At the same time, the Christian covenant is described as new in Jeremiah 31:31-34; it was both the continuation and designed fulfilment of the old, and in its superiority and plainer revelation of the Divine will was new. Hence the contrast between My covenant here and Thy covenant in the following verse. The covenant to be afterwards established shall be "an everlasting covenant."

16:59-63 After a full warning of judgments, mercy is remembered, mercy is reserved. These closing verses are a precious promise, in part fulfilled at the return of the penitent and reformed Jews out of Babylon, but to have fuller accomplishment in gospel times. The Divine mercy should be powerful to melt our hearts into godly sorrow for sin. Nor will God ever leave the sinner to perish, who is humbled for his sins, and comes to trust in His mercy and grace through Jesus Christ; but will keep him by his power, through faith unto salvation.Nevertheless I will remember my covenant with thee in the days of thy youth,.... The covenant made with them at Sinai, quickly after they came out of Egypt, when they were, both as a body politic and ecclesiastical, in their infant state; for, as Kimchi says, all the while they were in Egypt, and until they, came into the land of Canaan, were called the days of their youth; and to this covenant, which had the nature of a matrimonial contract, the, prophet refers when he speaks of the "love" of their "espousals", and the "kindness" of their "youth", Jeremiah 2:2; this covenant the Lord remembered, and made good his part, though they neglected theirs; and it was particularly remembered when Christ was made under this law, and became the fulfilling end of it to his people; yielding perfect obedience to it, and bearing the penalty of it in their room and stead; for here begins a declaration of the grace and mercy of God to the remnant, according to the election of grace, which were among this degenerate people, and whom the Lord had a special regard unto:

and I will establish unto thee an everlasting covenant; the covenant of grace, made with the Messiah and his spiritual seed; which is confirmed of God in Christ; ordered in all things and sure; whose promises are yea and amen in Christ; and the blessings of it, the sure mercies of David; a covenant that shall never be broken, made void, or removed; but will continue for ever. This is the new covenant, or the covenant of grace, as exhibited and administered under the New Testament; see Hebrews 8:8.
