Exodus 25:14

11 And thou shalt overlay it with pure gold, within and without shalt thou overlay it, and shalt make upon it a crown of gold round about.

12 And thou shalt cast four rings of gold for it, and put them in the four feet thereof; and two rings shall be on the one side of it, and two rings on the other side of it.

13 And thou shalt make staves of acacia wood, and overlay them with gold.

14 And thou shalt put the staves into the rings on the sides of the ark, wherewith to bear the ark.

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

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

17 And thou shalt make a mercy-seat of pure gold: two cubits and a half [shall be] the length thereof, and a cubit and a half the breadth thereof.
