2. Mose 3:13

When Moses had been thus emboldened by the assurance of divine assistance to undertake the mission, he inquired what he was to say, in case the people asked him for the name of the God of their fathers. The supposition that the people might ask the name of their fathers' God is not to be attributed to the fact, that as the Egyptians had separate names for their numerous deities, the Israelites also would want to know the name of their own God. For, apart from the circumstance that the name by which God had revealed Himself to the fathers cannot have vanished entirely from the memory of the people, and more especially of Moses, the mere knowledge of the name would not have been of much use to them. The question, "What is His name?" presupposed that the name expressed the nature and operations of God, and that God would manifest in deeds the nature expressed in His name. God therefore told him His name, or, to speak more correctly, He explained the name יהוה, by which He had made Himself known to Abraham at the making of the covenant (Gen 15:7), in this way, אהיה אשׁר אהיה, "I am that I am," and designated Himself by this name as the absolute God of the fathers, acting with unfettered liberty and self-dependence. This name precluded any comparison between the God of the Israelites and the deities of the Egyptians and other nations, and furnished Moses and his people with strong consolation in their affliction, and a powerful support to their confidence in the realization of His purposes of salvation as made known to the fathers. To establish them in this confidence, God added still further: "This is My name for ever, and My memorial unto all generations;" that is to say, God would even manifest Himself in the nature expressed by the name Jehovah, and by this He would have…

As prophecy had ceased for many ages before the coming of Christ, that the revival and perfection of it in that great prophet might be the more remarkable, so vision had ceased (for aught that appears) among the patriarchs for some ages before the coming of Moses, that God's appearances to him for Israel's salvation might be the more welcome; and in this chapter we have God's first appearance to him in the bush and the conference between God and Moses in that vision. Here is, I. The discovery God was pleased to make of his glory to Moses at the bush, to which Moses was forbidden to approach too near (Exo 3:1-5). II. A general declaration of God's grace and good-will to his people, who were beloved for their fathers' sakes (Exo 3:6). III. A particular notification of God's purpose concerning the deliverance of Israel out of Egypt. 1. He assures Moses it should now be done (Exo 3:7-9). 2. He gives him a commission to act in it as his ambassador both to Pharaoh (Exo 3:10) and to Israel (Exo 3:16). 3. He answers the objection Moses made of his own unworthiness (Exo 3:11, Exo 3:12). 4. He gives him full instructions what to say both to Pharaoh and to Israel (Exo 3:13-18). 5. He tells him beforehand what the issue would be (Exo 3:19, etc.).

3:13-22 Moses’ second protest was that he had inadequate knowledge. He did not know God’s name. This might mean that God’s personal name had not yet been revealed (see study notes on 6:2-3). It is also possible that Moses meant he did not know the secret, magic formula that a man of power might have been expected to make use of. Interest in such things was common in the ancient Near East. God’s direct response is almost a riddle, but the majority of his answer is a statement of his faithfulness in the past and a demonstration of his knowledge of the future. There is nothing magical about the name Yahweh. Knowledge of secret formulas and magic powers is not the issue; the issue is the character of God and his lordship of history. The reason there is “something about that name” is because of the incomparable character and nature of the one who bears it.
