C. F. Keil and Franz Delitzsch on Leviticus 14:13-14

Lev 14:13-14

After the slaying of the lamb in the holy place, as the trespass-offering, like the sin-offering, was most holy and belonged to the priest (see at Lev 7:6), the priest put some of its blood upon the tip of the right ear, the right thumb, and the great toe of the right foot of the person to be consecrated, in order that the organ of hearing, with which he hearkened to the word of the Lord, and those used in acting and walking according to His commandments, might thereby be sanctified through the power of the atoning blood of the sacrifice; just as in the dedication of the priests (Lev 8:24).
