'Side' in the Bible

And he shall kill it on the side of the altar northward before the LORD: and the priests, Aaron's sons, shall sprinkle his blood round about upon the altar.

And the priest shall bring it unto the altar, and wring off his head, and burn it on the altar; and the blood thereof shall be wrung out at the side of the altar:

And he shall sprinkle of the blood of the sin offering upon the side of the altar; and the rest of the blood shall be wrung out at the bottom of the altar: it is a sin offering.
