Exodus 40:3

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 make a vail of blue, and purple, and scarlet, and fine twined linen of cunning work: with cherubim shall it be made:

The ark, and the staves thereof, with the mercy seat, and the vail of the covering,

And he made a vail of blue, and purple, and scarlet, and fine twined linen: with cherubim made he it of cunning work.

And Bezaleel made the ark of shittim wood: two cubits and a half was the length of it, and a cubit and a half the breadth of it, and a cubit and a half the height of it: And he overlaid it with pure gold within and without, and made a crown of gold to it round about. And he cast for it four rings of gold, to be set by the four corners of it; even two rings upon the one side of it, and two rings upon the other side of it. And he made staves of shittim wood, and overlaid them with gold. And he put the staves into the rings by the sides of the ark, to bear the ark. And he made the mercy seat of pure gold: two cubits and a half was the length thereof, and one cubit and a half the breadth thereof. And he made two cherubim of gold, beaten out of one piece made he them, on the two ends of the mercy seat; One cherub on the end on this side, and another cherub on the other end on that side: out of the mercy seat made he the cherubim on the two ends thereof. And the cherubim spread out their wings on high, and covered with their wings over the mercy seat, with their faces one to another; even to the mercy seatward were the faces of the cherubim.

And he took and put the testimony into the ark, and set the staves on the ark, and put the mercy seat above upon the ark:

And he shall take of the blood of the bullock, and sprinkle it with his finger upon the mercy seat eastward; and before the mercy seat shall he sprinkle of the blood with his finger seven times.
