Exodus 25:21-23

King James Version

²¹ And thou shalt put the mercy seat above upon the ark; and in the ark thou shalt put the testimony that I shall give thee.

²² And there I will meet with thee, and I will commune with thee from above the mercy seat, from between the two cherubims which are upon the ark of the testimony, of all things which I will give thee in commandment unto the children of Israel.

²³ Thou shalt also make a table of shittim wood: two cubits shall be the length thereof, and a cubit the breadth thereof, and a cubit and a half the height thereof.
