Levitico 14:18

At sa natitirang langis na nasa kamay ng pari, ilalagay niya ito sa ulo ng tao na lilinisin, at gagawa ang pari ng pambayad kasalanan sa kanya sa harap ni Yahweh.

And the remnant of the oil that is in the priest’s hand he shall pour upon the head of him that is to be cleansed: and the priest shall make an atonement for him before the LORD.
