As this verse and what occurs in the first verse of the next chapter are materially the same, they shall be both explained here. God then says that the Jews would become a people to him, and that he would become a God to them. This mode of speaking is what we meet with everywhere in the Prophets; and it is very expressive, and includes the whole of true happiness. For when have we life, except when we become the people of God? We ought also to bear in mind that saying of the Psalmist, "Blessed are the people whose God is Jehovah." (Psalm 144:15) It confirms what I have just said, that a happy life is complete in all its parts, when God promises to be a God to us and takes us as his people. The Prophets, therefore, do not without reason so often inculcate this truth; for though nothing else might be wanting to us that could be expected, yet until we feel assured that God is a Father to us, and that we are his people, whatever happiness we may have, it will only end in misery. But the Prophet expresses himself more fully, when he says, At that time, that is, when God restored his Church, will I be a God to all the families of Israel They had been so scattered, that they were not one body; but God promises the gathering of that Church, from which the ten tribes had fallen off, when they revolted from the family of David. I cannot proceed farther now. Grant, Almighty God, that as thou hast manifested to us in thine only-begotten Son all the paternal goodness of which the fathers formerly tasted, and hast so really and fully exhibited it, that nothing more can be desired by us, -- O grant, that we may remain fixed in our trust in thee, and so cleave by true faith and in sincerity of heart to our Redeemer, that we may expect from him all things necessary for our salvation: and may we know that whatever may happen to us, we are still blessed, provided we enjoy this singular privilege, to call on thee as our Father through the name of the same thy Son. -- Amen.

This is the effect of Messiah's ministry. Men cannot become God's people, until there has been revealed one of themselves, a man, who can approach unto God, as being also God, and so can bridge over the gulf which separates the finite from the Infinite.

Ye shall be my people - The old covenant shall be renewed.

And ye shall be my people,.... For many hundred years the people of the Jews have been called "Loammi" or, "ye are not my people", Hosea 1:9; but now being converted, the covenant of God's grace shall be renewed, and a fresh manifestation and application of it made unto them; and they partaking of the grace of it, shall appear to be, and shall be, called the people of God, and shall behave as such, and fear and worship the Lord:
and I will be your God; will manifest his love to them, bestow his favours upon them, and take them under his care and protection. This is a summary of the covenant of grace, which will visibly take place when those people shall turn to the Lord, Romans 11:26.

ye shall be my people, &c.--The covenant shall be renewed between God and His people through Messiah's mediation (Jeremiah 30:21; Jeremiah 31:1, Jeremiah 31:33; Jeremiah 32:38; Ezekiel 11:20; Ezekiel 36:28).

Then Israel shall really become the people of the Lord, and the Lord shall be their God; thus the end of their divine calling shall be attained, and the salvation of Israel shall be complete; see on Jeremiah 7:23.
