1 Kings 8:21

Wherein is the covenant of the Lord - As it is said, 1 Kings 8:9 , that there was nothing in the ark but the two tables of stone, consequently these are called the Covenant, i.e., a sign of the covenant; as our Lord calls the cup the new covenant in his blood, that is, the sign of the new covenant: for This is my body implies, This is the sign or emblem of my body.
