Numbers 3:3

Whom he consecrated... — Literally, filled their hand. The rites of consecration are described at length in Exodus 29:1, where the command given to Moses is related. and in Leviticus 8:1, where the account is given of the actual consecration, on which occasion the appointed sacrificial offerings were placed by Moses in the hands of Aaron and in the hands of his sons. The act of consecration was performed by Moses in the case of Aaron’s sons, as well as in that of Aaron himself.
