Before the sanctuary and its vessels were dedicated for service, they were anointed with holy oil. On this occasion the miracle came to pass that twelve lugs of oil sufficed not only to anoint the sanctuary and its vessels, and Aaron and his two sons throughout the seven days of their consecration, but with this same oil were anointed all the successors of Aaron in the office of high priest, and several kings until the days of Josiah.

An especial miracle occurred when Aaron was anointed and on his pointed beard two drops of holy oil hung pendant like two pearls. These drops did not even disappear when he trimmed his beard, but rose to the roots of the hair. Moses at first feared that the useless waste of these drops of holy oil on Aaron's beard might be considered sacrilege, but a Divine voice quieted him. A Divine voice quieted Aaron, also, who likewise feared the accident that had turned the holy oil to his personal use.
