Immediately after the coming of Israel to Sinai, among the communications which expounded the covenant, preparatory to its sealing, the Lord said to them, “Behold I send an Angel before thee, to keep thee in the way, and to bring thee into the place which I have prepared. Beware of him and obey his voice. Provoke him not, for he will not pardon your transgressions; for my name is in him.”—Ex. xxiii, 20, 21. This Angel is by the Lord elsewhere called “My Presence” (Compare Ex. xiv, 19; xxxii, 34; xxxiii, 2, 14, 15), and by Isaiah, “the Angel of His presence.”—Isa. lxiii, 9. He is thus announced to Israel as sent to be God’s servant in the fulfilling of the Sinai covenant, and is hence by the prophet called “the Messenger of the covenant.” Another line of facts leads in the same direction. When, at the mount, Israel was overwhelmed with the terror of the great fire and of God’s audible voice, and entreated Moses, “Speak thou with us, and we will hear; but let not God speak with us lest we die” (Ex. xx, 19; Deut. v, 22-27), their proposal thus to accept Moses as Mediator between them and God was graciously approved. “They have well said, all that they have spoken.”—Deut. v, 28. Moses was accepted in that office, and Israel dismissed from the assembly at the mount. (Ib. 28-31.) But, afterward, Moses revealed to them how much more richly their abasement and prayer had been answered than they had asked or imagined. “The Lord thy God will raise up unto thee a prophet from the midst of thee, of thy brethren like unto me; unto him ye shall hearken; according to all that thou desiredst of the Lord thy God in Horeb, in the day of the assembly, saying, Let me not hear again the voice of the Lord my God, neither let me see this great fire any more that I die not. And the Lord said unto me, They have well spoken that which they have spoken. I will raise them up a prophet from among their brethren, like unto thee, and will put my words in His mouth; and He shall speak unto them all that I shall command Him.”—Deut. xviii, 15-18. Compare John xiv, 31; xvii, 8, 14.
