Another Kohein Lends a HandBy Rabbi Jack Abramowitz
The kohein places some of the sheep’s blood on the person’s right ear, right thumb and right big toe. He then pours some of the oil into another kohein’s left hand. That kohein dips into the oil with his right index finger and sprinkles seven times. Oil then goes on the person’s right ear, thumb and toe; the rest of the oil in the kohein’s hand is placed on the person’s head.
The female sheep is the offered as a korban chatas (sin offering), the second male sheep is offered as a korban olah (burnt offering) and the flour is offered as a korban mincha (flour offering, natch!). After that, the process is complete and the person is clean.
