民数記 3:9

נתונים המה לו THEY ARE GIVEN UNTO HIM as a help. מאת בני ישראל has the same meaning as FROM AMONG THE MIDST OF (מתוך) THE CHILDREN OF ISRAEL, that is to say, they have been set aside from among the rest of the congregation for this purpose by a decree of the Omnipresent, and it is He who gave them (the Levites) to him, as it is said (Numbers 8:19) “And “I” have given the Levites as a gift [to Aaron]”.

And thou shalt give the Levites to Aharon and to his sons: they are wholly given to him out of the children of Yisra᾽el.
