Numbers 4:3-5

New International Reader's Version

³ Count all the men 30 to 50 years old. Those are the men who must come and serve at the tent of meeting.

⁴ “Here is the work the men of Kohath must do at the tent of meeting. They must take care of the things that are very holy. ⁵ When the camp is ready to move, Aaron and his sons must go into the tent. They must take down the curtain that hides the ark where the tablets of the covenant law are kept. They must cover the ark with the curtain.
