Exodus 25:10-22 NIV
“Have them make an ark of acacia wood—two and a half cubits long, a cubit and a half wide, and a cubit and a half high. Overlay it with pure gold, both inside and out, and make a gold molding around it. Cast four gold rings for it and fasten them to its four feet, with two rings on one side and two rings on the other. Then make poles of acacia wood and overlay them with gold. Insert the poles into the rings on the sides of the ark to carry it. The poles are to remain in the rings of this ark; they are not to be removed. Then put in the ark the tablets of the covenant law, which I will give you.
“Make an atonement cover of pure gold—two and a half cubits long and a cubit and a half wide. And make two cherubim out of hammered gold at the ends of the cover. Make one cherub on one end and the second cherub on the other; make the cherubim of one piece with the cover, at the two ends. The cherubim are to have their wings spread upward, overshadowing the cover with them. The cherubim are to face each other, looking toward the cover. Place the cover on top of the ark and put in the ark the tablets of the covenant law that I will give you. There, above the cover between the two cherubim that are over the ark of the covenant law, I will meet with you and give you all my commands for the Israelites.
