We are told how Moshe was to inaugurate Aharon as Kohen Gadol and his sons into the priesthood. One of the acts was to sacrifice a ram and to take from its blood and smear it on the lobe of the right ear of Aharon and his sons, on the thumb of their right hand and on the big toe of their right foot.
This was a very significant symbolic act. Aharon and his sons and the Kohanim who followed in future generations were to serve as spiritual leaders of the Jewish people. Placing the blood on the ear, the hand and the leg of the Kohanim indicated that they must ever be mindful of the people to be prepared to serve them in every way.
They must listen attentively to all their needs. They must be ready to extend their hand to help in whatever way was necessary. They must be prepared to go and run to help those who require their assistance.
This applied to Kohanim in generations past when they were the leaders. Today it applies to our current leaders. They must be ready to know what our people need, to be ready to extend the help, and be prepared to reach out to meet the necessary needs of our people.
