Shemot 29:20

Then shalt thou slaughter (shachat) the ayil, and take of his dahm, and put it upon the lobe of the right ear of Aharon, and upon the lobe of the right ear of his banim, and upon the thumb of their right yad, and upon the bohen of their right foot, and sprinkle the dahm upon the Mizbe'ach, all around.
