This they shall give, every one that passes among them that are numbered, half a shekel after the shekel of the sanctuary: (a shekel is twenty gerahs:) a half shekel shall be the offering of the LORD.
The rich shall not give more, and the poor shall not give less than half a shekel, when they give an offering unto the LORD, to make an atonement for your souls.
And you shall take the atonement money of the children of Israel, and shall appoint it for the service of the tabernacle of meeting; that it may be a memorial unto the children of Israel before the LORD, to make an atonement for your souls.
