Exodus 25:21

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.

Ver. 21. Above upon the ark.] The ark covering the law within it, the mercy seat upon it, and over them two cherubims covering one another, did typify Christ covering the curses of the law, in whom is the ground of all mercy; "which things the angels desire to pry into," 1Pe 1:12 as into the pattern of God's deep wisdoms. Eph 3:10
