For there were many in the assembly that had not sanctified themselves: therefore the Levites had the charge of killing the passovers for every one that was not clean, to sanctify them unto Jehovah.

Since there were many in the assembly who had not consecrated themselves, the Levites were in charge of slaughtering the Passover lambs for every unclean person to consecrate the lambs to the LORD.

for many are in the assembly who have not sanctified themselves, and the Levites are over the slaughtering of the passover-offerings for every one not clean, to sanctify him to Jehovah:

For there were many in the congregation that were not hallowed; therefore the Levites had the charge of the slaughtering of the passover-lambs for every one not clean, to hallow them unto Jehovah.
