Exodus 40:20

As the LORD commanded Moses, so Aaron laid it up before the Testimony, to be kept.

And thou shalt put into the ark the testimony which I shall give thee. And thou shalt make a mercy seat of pure gold: two cubits and a half shall be the length thereof, and a cubit and a half the breadth thereof. And thou shalt make two cherubim of gold, of beaten work shalt thou make them, in the two ends of the mercy seat. And make one cherub on the one end, and the other cherub on the other end: even of the mercy seat shall ye make the cherubim on the two ends thereof. And the cherubim shall stretch forth their wings on high, covering the mercy seat with their wings, and their faces shall look one to another; toward the mercy seat shall the faces of the cherubim be. 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 he gave unto Moses, when he had made an end of communing with him upon mount Sinai, two tables of testimony, tables of stone, written with the finger of God.

I delight to do thy will, O my God: yea, thy law is within my heart.

And Jesus answering said unto him, Suffer it to be so now: for thus it becometh us to fulfil all righteousness. Then he suffered him.
