กันดารวิถี 6:27

ושמו את שמי AND THEY SHALL PUT MY NAME [UPON THE CHILDREN OF ISRAEL] — i.e. they shall bless them by the Proper Name of God (i. e. when uttering the blessings they shall use the Tetragrammaton and no substitute for it) (Sifrei Bamidbar 43). ואני אברכם AND I WILL BLESS THEM — i.e. I will bless the Israelites: I will give My approval to the priests’ blessings (lit., I will agree with the priests). — Another explanation of “And I will bless them” is: “And I will bless the priests (Chullin 49a).

וְשָׂמ֥וּ אֶת־שְׁמִ֖י עַל־בְּנֵ֣י יִשְׂרָאֵ֑ל וַאֲנִ֖י אֲבָרְכֵֽם׃ {ס}        

And they shall put my name upon the children of Yisra᾽el; and I will bless them.
