Exodus 3:2

“And the Angel of the Lord appeared unto him, etc.] Not a created angel, but the Angel of God’s presence and covenant, the eternal Word and Son of God; since he is afterwards expressly called Jehovah, and calls himself the God of Abraham, Isaac, and Jacob, which a created angel would never do: the appearance was, in a flame of fire, out of the midst of a bush; not in a tall, lofty, spreading oak or cedar, but in a low thorny bramble bush, which it might have been thought would have been consumed in an instant of time: and he looked, and, behold, the bush burned with fire, and the bush [was] not consumed; this was not imaginary, but a real thing; there was such a bush, and Jehovah appeared in…”

“the angel of the Lord appeared unto him in a flame of fire--It is common in Scripture to represent the elements and operations of nature, as winds, fires, earthquakes, pestilence, everything enlisted in executing the divine will, as the "angels" or messengers of God. But in such cases God Himself is considered as really, though invisibly, present. Here the preternatural fire may be primarily meant by the expression "angel of the Lord"; but it is clear that under this symbol, the Divine Being was present, whose name is given (Exo 3:4, Exo 3:6), and elsewhere called the angel of the covenant, Jehovah-Jesus. out of the midst of a bush--the wild acacia or thorn, with which that desert abounds,…”

“The angel of the Lord - See the note at Genesis 12:7. What Moses saw was the flame of fire in the bush; what he recognized therein was an intimation of the presence of God, who maketh a flame of fire His angel. Compare Psalms 104:4. The words which Moses heard were those of God Himself, as all ancient and most modern divines have held, manifested in the Person of the Son. Of a bush - Literally, of the bush or “seneh,” a word which ought perhaps to be retained as the proper name of a thorny shrub common in that district, a species of acacia. return to 'Top of Page'”

“And the angel of the Lord appeared to him - It was an extraordinary manifestation of the divine glory; what was visible was produced by the ministry of an angel, but he heard God in it speaking to him. In a flame of fire - To shew that God was about to bring terror and destruction to his enemies, light and heat to his people, and to display his glory before all. And the bush burned, and yet was not consumed - An emblem of the church now in bondage in Egypt, burning in the brick - kilns, yet not consumed; cast down, but not destroyed. Exodus 3:3”

“3:2 Technically, the angel of the Lord is the Lord’s officially authorized envoy, but the expression may be used more broadly of other visible manifestations of the Lord (see Gen 16:9-13; Judg 13:3, 6, 21-22). • In the Bible, blazing fire often represents God’s transcendent holiness (see Exod 19:18; Gen 15:17; 1 Kgs 18:38-39; Isa 33:14). • didn’t burn up: This may show that God does not wish to consume the vehicle that he sets ablaze for his purposes.”

“angel: Exo 3:4, Exo 3:6; Gen 16:7-13, Gen 22:15, Gen 22:16, Gen 48:16; Deu 33:16; Isa 63:9; Hos 12:4, Hos 12:5; Mal 3:1; Luk 20:37; Act 7:30-35 bush burned: Gen 15:13-17; Deu 4:20; Psa 66:12; Isa 43:2, Isa 53:10, Isa 53:11; Dan 3:27; Zac 13:7; Joh 1:14; Rom 8:3; Co2 1:8-10 Exodus 3:3”

“Here, at Horeb, God appeared to Moses as the Angel of the Lord "in a flame of fire out of the midst of the thorn-bush" (סנה, βάτος, rubus), which burned in the fire and was not consumed. אכּל, in combination with איננּוּ, must be a participle for מאכּל. When Moses turned aside from the road or spot where he was standing, "to look at this great sight" (מראה), i.e., the miraculous vision of the bush that was burning and yet not burned up, Jehovah called to him out of the midst of the thorn-bush, "Moses, Moses (the reduplication as in Gen 22:11), draw not nigh hither: put off thy shoes from off thy feet, for the place whereon thou standest is holy ground" (אדמה).
