Exodus 25:7 (KJV)

Speak unto the children of Israel, that they bring me an offering: of every man that giveth it willingly with his heart ye shall take my offering.

And this is the offering which ye shall take of them; gold, and silver, and brass,

And blue, and purple, and scarlet, and fine linen, and goats' hair,

And rams' skins dyed red, and badgers' skins, and shittim wood,

Oil for the light, spices for anointing oil, and for sweet incense,

And let them make me a sanctuary; that I may dwell among them.

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.
