Doctrine of Life # 60
60. That the stone tablets on which the law was written were called the Tablets of the Covenant, and that because of them the Ark was called the Ark of the Covenant, the law itself being the covenant, see Numbers 10:33; Deuteronomy 4:13, 23, 5:2-3, 9:9; Joshua 3:11; 1 Kings 8:19, 21; Revelation 11:19. And many other places.
The law was called a covenant because a covenant symbolizes conjunction. We are accordingly told regarding the Lord that He would be “as a covenant to the people” (Isaiah 42:6, 49:8). He is called, too, “the Messenger of the covenant” (Malachi 3:1), and His blood “the blood of the covenant” (Matthew 26:28, Zechariah 9:11, Exodus 24:4-10). That is why the Word is called the Old Covenant and New Covenant.
Covenants are also made as testaments of love, friendship, and fellowship, thus for the sake of conjunction.
