Exodus 29:5 - Clarke's commentary and critical notes on the Bible

And thou shalt take the garments, and put upon Aaron the coat, and the robe of the ephod, and the ephod, and the breastplate, and gird him with the curious girdle of the ephod: Thou shalt take the garments - As most offices of spiritual and secular dignity had appropriate habits and insignia, hence, when a person was appointed to an office and habited for the purpose, he was said to be invested with that office, from in, used intensively, and vestio, I clothe, because he was then clothed with the vestments peculiar to that office.
