הִנֵּ֥ה בָרֵ֖ךְ לָקָ֑חְתִּי וּבֵרֵ֖ךְ וְלֹ֥א אֲשִׁיבֶֽנָּה׃
Ecco, mi è proibito benedire; E quando ha benedetto, non posso richiamarlo.
Targum Jonathan on Numbers
Behold, from the mouth of the Holy Word I have received the benediction, and their appointed benediction I cannot restrain from them.
Targum Jerusalem
Behold, I have received to bless Israel, and I cannot restrain the blessings from them.
