Exodus 30:10–16

¹⁰And Aaron shall make atonement upon the horns of it once in the year; with the blood of the sin-offering of atonement once in the year shall he make atonement for it throughout your generations: it is most holy unto Jehovah.

¹¹And Jehovah spake unto Moses, saying, ¹²When thou takest the sum of the children of Israel, according to those that are numbered of them, then shall they give every man a ransom for his soul unto Jehovah, when thou numberest them; that there be no plague among them, when thou numberest them. ¹³This they shall give, every one that passeth over unto them that are numbered, half a shekel after the shekel of the sanctuary; (the shekel is twenty gerahs), half a shekel for an offering to Jehovah. ¹⁴Every one that passeth over unto them that are numbered, from twenty years old and upward, shall give the offering of Jehovah. ¹⁵The rich shall not give more, and the poor shall not give less, than the half shekel, when they give the offering of Jehovah, 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 Jehovah, to make atonement for your souls.
