and you shall kill the ram and take part of its blood and put it on the tip of the right ear of Aaron and on the tips of the right ears of his sons, and on the thumbs of their right hands and on the great toes of their right feet, and throw the rest of the blood against the sides of the altar.
The ceremonies for consecrating Aaron and his sons had to be set down in detail so that they themselves would grasp the weight of what God called them to, and the people would learn to honor the office and keep their hands off it. The Hebrew word for consecrating means filling the hand, which tells us ministers have their hands full, no time for trifling, their work is so great and constant.

Commenting on Exodus 29:1-37
The ear, thumb, and toe receive the blood to teach the priest that he must listen attentively to the Lord's word, act with holy hands, and walk in pure conversation, yet since the priests themselves remain imperfect, they need the precious blood of the great High Priest sprinkled on them continually to cleanse what they cannot perfect.
