Exodus 30:10-12

Darby Translation

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

¹¹ And Jehovah spoke to Moses, saying,

¹² When thou shalt take the sum of the children of Israel according to those of them that are numbered, then shall they give every man a ransom for his soul to Jehovah on their being numbered, that there be no plague among them on their being numbered.
