40to offer burnt offerings to the Lord on the altar of burnt offering continually, morning and evening, in accordance with all that is written in the Law of the Lord, which He commanded Israel.

41With them were Heman and Jeduthun, and the rest who were chosen and designated by name, to give thanks to the Lord, for His lovingkindness endures forever.
