⁴ And he appointed certain of the Levites to minister before the ark of the Lord, and to record, and to thank and praise the Lord God of Israel:

¹³ The sons of Amram; Aaron and Moses: and Aaron was separated, that he should sanctify the most holy things, he and his sons for ever, to burn incense before the Lord, to minister unto him, and to bless in his name for ever.

¹¹ My sons, be not now negligent: for the Lord hath chosen you to stand before him, to serve him, and that ye should minister unto him, and burn incense.

² And Hezekiah appointed the courses of the priests and the Levites after their courses, every man according to his service, the priests and Levites for burnt offerings and for peace offerings, to minister, and to give thanks, and to praise in the gates of the tents of the Lord.

134 Behold, bless ye the Lord, all ye servants of the Lord, which by night stand in the house of the Lord.
