¹⁰Once a year Aaron shall perform the rite of atonement on its horns. Throughout your generations he shall perform the atonement for it once a year with the blood of the atoning purification offering. It is most holy to the Lord.”^*

The Half Shekel for the Sanctuary

¹¹The Lord spoke to Moses, ¹²“When you take a census of the Israelites to register them, at registration all of them shall give a ransom for their lives to the Lord, so that no plague may come upon them for being registered.^{* 13}This is what each one who is registered shall give: half a shekel according to the shekel of the sanctuary (the shekel is twenty gerahs), half a shekel as an offering to the Lord.^{* 14}Each one who is registered, from twenty years old and up, shall give the Lord’s offering. ¹⁵The rich shall not give more and the poor shall not give less than the half shekel, when you bring this offering to the Lord to make atonement for your lives.^{* 16}You shall take the atonement money from the Israelites and shall designate it for the service of the tent of meeting; before the Lord it will be a reminder to the Israelites of the ransom given for your lives.”^*
