Exodus 30:3-5

And thou shalt overlay it with pure gold, the top thereof, and the sides thereof round about, and the horns thereof; and thou shalt make unto it a crown of gold round about. {top: Heb. roof} {sides: Heb. walls} And two golden rings shalt thou make to it under the crown of it, by the two corners thereof, upon the two sides of it shalt thou make {it}; and they shall be for places for the staves to bear it withal. {corners: Heb. ribs} And thou shalt make the staves {of} shittim wood, and overlay them with gold.
