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. Then shall they give every man a ransom for his soul - This was a very important ordinance, and should be seriously considered. See Exodus 30:13 (note).
