For the Lord hath chosen Jacob unto himself: Israel for his own possession.

“"For the Lord has chosen Jacob to Himself, Israel for His own possession" [Psalm 135:4]....Let not Jacob therefore extol himself, let him not boast himself, or ascribe it to his own merits. He was known before, predestinated before, elected before, not elected for his own merits, but found out, and gifted with life by the grace of God. So with all the Gentiles; for how did the wild-olive deserve, that it should be grafted in, from the bitterness of its berries, the barrenness of its wildness? It was the wood of the wilderness, not of the Lord's field, and yet He of His mercy grafted the wild-olive into the (true) olive. But up to this time the wild-olive was not grafted in.”

“For the Lord hath chosen Jacob unto himself,.... To be his own special people, and not another's; for his own service, and for his glory; and to be an habitation for himself, and to be for ever with him. This is not to be understood personally of Jacob, though a chosen vessel of mercy; nor of his natural posterity as such, though chosen as a nation to outward favours; for not all they, only some of them, were chosen to special grace and glory, a remnant according to the election of grace: but mystical and spiritual Jacob and Israel are meant, even the whole church and people of God, whether Jews or Gentiles; these God has chosen, of his own free grace and good will, to all the blessings of grace and glory, and that from all eternity; which choice will remain firm and immutable, in time and for ever; and therefore is worthy of praise and thanksgiving, now, and to all eternity; and Israel for his peculiar treasure; by whom they are accounted as such; even as the peculiar treasure of kings, as silver, gold, jewels, and precious stones; as his inheritance, his portion, and peculiar people; see Exo 19:5.”

“Possession. Hebrew, “jewel,” “property.” Chaldean, “well-beloved.” See Deuteronomy lii. 8., and Ecclesiasticus xvii. 14. (Calmet) — The first patriarchs corresponded with God’s goodness: but their descendants were for the most part ungrateful: so that Christians have now entered into their place, and must praise God.
