Exodus 30:5

Its length shall be a cubit, and its width a cubit. It shall be square, and its height shall be two cubits. Its horns shall be of one piece with it.

You shall overlay it with pure gold, its top, its sides around it, and its horns; and you shall make a gold molding around it.

You shall make two golden rings for it under its molding; on its two ribs, on its two sides you shall make them; and they shall be for places for poles with which to bear it.

You shall put it before the veil that is by the ark of the covenant, before the mercy seat that is over the covenant, where I will meet with you.

Aaron shall burn incense of sweet spices on it every morning. When he tends the lamps, he shall burn it.

When Aaron lights the lamps at evening, he shall burn it, a perpetual incense before the LORD throughout your generations.
