Exodus

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.

Take the sum of all the congregation of the children of Israel, from twenty years old and upward, throughout their fathers’ house, all that are able to go to war in Israel.

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.
