60. That the tables of stone on which the Law was written were called "the tables of the covenant," and that from them the ark was called "the ark of the covenant," and the Law itself "the covenant," see Num. 10:33; Deut. 4:13, 23; 5:2, 3; 9:9; Josh. 3:11; 1 Kings 8:19, 21; Rev. 11:19; and in many other places. The reason why the Law was called the "covenant," is that "covenant" signifies conjunction; and it is therefore said of the Lord that:
He shall be for a covenant to the people (Isa. 42:6; 49:8; and He is called:
The messenger of the covenant (Mal. 3:1);
and His blood:
The blood of the covenant (Matt. 26:28; Zech. 9:11; Exod. 24:4-10).
And therefore the Word is called the "Old Covenant," and the "New Covenant." Moreover covenants are made for the sake of love, friendship, association, and thus for the sake of conjunction.
