’When thou takest the sum of the children of Israel, according to 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.
Targum Jonathan on Exodus
When thou takest the sum of the sons of Israel according to their number, they shall give every man the ransom of their souls before the Lord when thou numberest them; that there may not be among them the calamity of death when thou dost number them.
Targum Jerusalem
When thou takest the head of the number of the sums of the sons of Israel.
