Numbers 3:3

These [are] the names of the sons of Aaron, the priests that
were anointed
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 ) .
