Exodus 30:16-18

American Standard Version

¹⁶ And thou shalt take the atonement money from the children of Israel, and shalt appoint it for the service of the tent of meeting; that it may be a memorial for the children of Israel before Jehovah, to make atonement for your souls.

¹⁷ And Jehovah spake unto Moses, saying, ¹⁸ Thou shalt also make a laver of brass, and the base thereof of brass, whereat to wash. And thou shalt put it between the tent of meeting and the altar, and thou shalt put water therein.
