Exodus 25:5 (KJV)

And the LORD spake unto Moses, saying,

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,

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

Onyx stones, and stones to be set in the ephod, and in the breastplate.

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.
