Parallel
2 Chronicles 30:17
Brenton's English Septuagint · Berean Standard Bible
For a great part of the congregation was not sanctified; and the Levites were [ready] to kill the passover for every one who could not sanctify himself to the Lord.
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.
