Numbers 4:4 BBE

²  Let the sons of Kohath, from among the sons of Levi, be numbered by their families, in the order of their fathers' houses;

³  All those from thirty to fifty years old who are able to do the work of the Tent of meeting.

⁴  And this is to be the work of the sons of Kohath in connection with the most holy things.

⁵  When all the people go forward, Aaron is to go in with his sons, and take down the veil of the curtain, covering the ark of witness with it;

⁶  And putting over it the leather cover and over that a blue cloth; and putting its rods in place.
