Exodus 19:3

Moses went up unto God— The Deity having made his presence known by the usual symbol, Moses ascended to that part of the Mountain where the Lord manifested himself, and from whence he issued his sacred mandates. We have so frequently observed, that the Divine Person, who is called God, and also Lord or Jehovah, and who appeared throughout the Old Testament, was CHRIST, the Angel of the Covenant; that it may be unnecessary to remark, that the Angel, mentioned Acts 7:38 means the same person. The Lord being about to deliver a system of laws to the Israelites, introduces it with a pathetic declaration of what he had already performed for them, and with the most engaging promises of what he would hereafter perform, if they would obey his covenant, (Exodus 19:5.) and we find, all through the Jewish economy, that national happiness or misery was the invariable consequence of their obedience or neglect.
