Exodus 25:21-25

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.

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.

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.

And thou shalt overlay it with pure gold, and make thereto a crown of gold round about.

And thou shalt make unto it a border of an hand breadth round about, and thou shalt make a golden crown to the border thereof round about.
