TSK · Leviticus 4:29

And he shall bring the bullock unto the door of the tabernacle of the congregation before the LORD; and shall lay his hand upon the bullock's head, and kill the bullock before the LORD.

And he shall lay his hand upon the head of the goat, and kill it in the place where they kill the burnt offering before the LORD: it [is] a sin offering.

The trespass money and sin money was not brought into the house of the LORD: it was the priests'.

For [it is] not possible that the blood of bulls and of goats should take away sins.
