'Side' in the Bible

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

And the priest shall bring it unto the altar, and wring off its head, and burn it on the altar; and the blood thereof shall be drained out on 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 drained out at the base of the altar: it is a sin-offering.
