Leviticus 4:2-6

“Speak to the sons of Israel, saying, ‘If a person sins unintentionally in any of the things which the Lord has commanded not to be done, and commits any of them,

if the anointed priest sins so as to bring guilt on the people, then he is to offer to the Lord a bull without defect as a sin offering for his sin which he has committed.

He shall bring the bull to the doorway of the tent of meeting before the Lord, and he shall lay his hand on the head of the bull and slaughter the bull before the Lord.

Then the anointed priest is to take some of the blood of the bull and bring it to the tent of meeting,

and the priest shall dip his finger in the blood and sprinkle some of the blood seven times before the Lord, in front of the veil of the sanctuary.
