Exodus 25:10-16

10And they shall make an ark of acacia-wood; two cubits and a half the length thereof, and a cubit and a half the breadth thereof, and a cubit and a half the height thereof.

11And thou shalt overlay it with pure gold: inside and outside shalt thou overlay it; and shalt make upon it a border of gold round about.

12And cast four rings of gold for it, and put [them] at the four corners thereof, that two rings may be upon the one side thereof and two rings upon the other side thereof.

13And make staves of acacia-wood and overlay them with gold.

14And put the staves into the rings upon the sides of the ark, that the ark may be borne with them.

15The staves shall be in the rings of the ark: they shall not come out from it.

16And thou shalt put into the ark the testimony that I shall give thee.
