SEV Biblia, Chapter 3:3
Estos son los nombres de los hijos de Aarón, sacerdotes ungidos; cuyas manos él llenó para administrar el sacerdocio.
John Gill's Bible Commentary
Ver. 3. These [are] the names of the sons of Aaron, the priests that were anointed , etc.] With the holy, anointing oil, with which they were anointed when, Aaron was and they only, (see Exodus 30:30); whom he consecrated to minister in the priest’s office ; that is, whom Moses consecrated, by anointing them, putting the priest’s garments on them, offering sacrifice for them, and filling their hands with sacrifices which is the phrase here used for consecration: (see Exodus 29:15-24).
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.
