John Gill Bible Commentary

And they shall put my name upon the children of Israel,.... Call them by his name, the people of the Lord; call upon the name of the Lord to bless them, and pronounce the blessing on them in the name of the Lord, in or by the name Jehovah, as Jarchi, three times used in this form of blessing: and I will bless them; really and truly bless them bless them with blessings indeed; with all sorts of blessings temporal and spiritual; with solid and substantial ones; and such are blessed, and will remain so, their blessings are irrevocable and irreversible; and unless the Lord blesses, in vain do the priests bless, or any of his ministers pronounce a blessing; theirs lies in words and wishes, his in real facts; they can only pray and wish for the blessing, it is he only that can give it, and can ratify and confirm what they declare and pronounce, according to his revealed word. Some refer the relative "them" to the priests, as if the sense was, I will bless the priests that bless Israel, for God will bless them that bless his people; but Aben Ezra thinks it belongs both to Israel, and to the priests, that God would confirm and establish the blessing of the priests pronounced on Israel, and bless the priests also, who needed the divine blessing as well as the people, and being found in the way of their duty, might expect it: the Targum of Jonathan is,"I will bless them in my Word;''his essential Word, Christ, in whom his chosen ones are blessed with all spiritual blessings, and who is the promised seed, in whom all nations of the earth shall be blessed.
