Exodus 25:20-22

201The cherubim shall have their wings spread upward, covering the mercy seat with their wings and 2facing one another; the faces of the cherubim are to be turned toward the mercy seat. 213You shall put the mercy seat 4on top of the ark, and 5in the ark you shall put the testimony which I will give to you. 226There I will meet with you; and from above the mercy seat, from 7between the two cherubim which are upon the ark of the testimony, I will speak to you about all that I will give you in commandment for the sons of Israel.
