Exodus 25:14 (KJV)

According to all that I shew thee, after the pattern of the tabernacle, and the pattern of all the instruments thereof, even so shall ye make it.

And they shall make an ark of shittim wood: two cubits and a half shall be the length thereof, and a cubit and a half the breadth thereof, and a cubit and a half the height thereof.

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.

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

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

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

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

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.

And thou shalt make two cherubims of gold, of beaten work shalt thou make them, in the two ends of the mercy seat.

And make one cherub on the one end, and the other cherub on the other end: even of the mercy seat shall ye make the cherubims on the two ends thereof.
