Here is how God obliged Moses: Besides passing before him and revealing His form except for His face, He preaches to him what amounted to a sermon on His name—on the third commandment! He expounds eleven attributes: Yahweh, El, the Merciful Being, the Gracious One, the Longsuffering One, the Mighty One, the Bountiful Being, the True One, the Preserver of Bountifulness, He who bears away iniquity, and He who visits iniquity.
God did not demonstrate for Moses His power and majesty, but His love, His way of relating to His creation. In other words, the glory of God is the manifestation of His character, His nature, His manner of dealing with His people, His potential children. His names are signposts of His attributes and character. They advertise His nature. They remind us of what we can expect Him to do and what He requires.
