SEV Biblia, Chapter 3:9
Y darás los levitas a Aarón y a sus hijos; le son enteramente dados de entre los hijos de Israel.
John Gill's Bible Commentary
Ver. 9. And thou shalt give the Levites unto Aaron and to his sons , etc.] To be their ministers and servants: they [are] wholly given unto him out of the children of Israel : even all of them entirely, none excepted; the whole tribe which were not in the priestly office; those were separated from the rest of the tribes of Israel, and appointed for the service of the priests: or they were “given, given” f16 ; which is repeated not only to show that they were wholly given, as we render it, but to denote the certainty of it, that they were really given; and especially to declare the freeness of the gift; the priests had them as free gifts, nor did they pay them any thing for, their service; they were maintained another way, namely, by the tithes of the people; and indeed the priests received a tithe out of the tithe of the Levites; so far were they from contributing any thing to their support, or in consideration of the service they did them.
Matthew Henry Commentary
Verses 1-13 - There was much work belonging to the priests' office, and there wer now only Aaron and his two sons to do it; God appoints the Levites to attend them. Those whom God finds work for, he will find help for. The Levites were taken instead of the first-born. When He that made us saves us, as the first-born of Israel were saved, we are laid unde further obligations to serve him faithfully. God's right to us by redemption, confirms the right he has to us by creation.
