The law concerning the consecration of Aaron and his sons to the priest's office, which was to be done with a great deal of ceremony and solemnity, that they themselves might be duly affected with the greatness of the work to which they were called, and that the people also might learn to magnify the office and none might dare to invade it. 1.
Commenting on Exodus 29:1-37
And thou shall take the other ram,.... The other of the two that was left, Exo 29:1, and Aaron and his sons shall put their hands on the head of the ram, as they were to do, and did, upon the head of the other; See Gill on Exo 29:15.
The other ram - There were two rams brought on this occasion: one was for a burnt-offering, and was to be entirely consumed; the other was the ram of consecration, Exo 29:22, איל מלאים eil milluim, the ram of filling up, because when a person was dedicated or consecrated to God, his hands were filled with some particular offering proper for the occasion, which he presented to God.
