Exodus

¹⁴Every one that passeth over unto them that are numbered, from twenty years old and upward, shall give the offering of the Lord. ¹⁵The rich shall not give more, and the poor shall not give less, than the half shekel, when they give the offering of the Lord, to make atonement for your souls. ¹⁶And 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 the Lord, to make atonement for your souls. ¹⁷And the Lord spake unto Moses, saying, ¹⁸Thou shalt also make a laver of brass, and the base thereof of brass, to wash withal: and thou shalt put it between the tent of meeting and the altar, and thou shalt put water therein. ¹⁹And Aaron and his sons shall wash their hands and their feet thereat: ²⁰when they go into the tent of meeting, they shall wash with water, that they die not; or when they come near to the altar to minister, to burn an offering made by fire unto the Lord:
