When thou takest the sum of the children of Israel after their number, then shall they give every man a ransom for his soul unto the Lord, when thou numberest them; that there be no plague among them, when [thou] numberest them. (30:12)

This they shall give, every one that passeth among them that are numbered, half a shekel after the shekel of the sanctuary: (a shekel [is] twenty gerahs:) an half shekel [shall be] the offering of the Lord. (30:13)

Every one that passeth among them that are numbered, from twenty years old and above, shall give an offering unto the Lord. (30:14)

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. (30:15)

And thou shalt take the atonement money of the children of Israel, and shalt appoint it for the service of the tabernacle of the congregation; that it may be a memorial unto the children of Israel before the Lord, to make an atonement for your souls. (30:16)

--Leviticus--

If a soul commit a trespass, and sin through ignorance, in the holy things of the Lord; then he shall bring for his trespass unto the Lord a ram without blemish out of the flocks, with thy estimation by shekels of silver, after the shekel of the sanctuary, for a trespass offering: (5:15)

And he shall make amends for the harm that he hath done in the holy thing, and shall add the fifth part thereto, and give it unto the priest: and the priest shall make an atonement for him with the ram of the trespass offering, and it shall be forgiven him. (5:16)

--2 Kings--

The trespass money and sin money was not brought into the house of the Lord: it was the priests'. (12:16)
