19. the angel of God—that is, the pillar of cloud [see on Ex 13:21]. The slow and silent movement of that majestic column through the air, and occupying a position behind them must have excited the astonishment of the Israelites (Isa 58:8). It was an effectual barrier between them and their pursuers, not only protecting them, but concealing their movements. Thus, the same cloud produced light (a symbol of favor) to the people of God, and darkness (a symbol of wrath) to their enemies (compare 2Co 2:16).

     20-25. Behold, I send an Angel before thee, to keep thee in the way—The communication of these laws, made to Moses and by him rehearsed to the people, was concluded by the addition of many animating promises, intermingled with several solemn warnings that lapses into sin and idolatry would not be tolerated or passed with impunity.

     21. my name is in him—This angel is frequently called Jehovah and Elohim, that is, God.

     6-8. The experience of these servants of God is cited for encouragement.

     7. cloudy pillar—the medium of divine intercourse (Ex 33:9; Nu 12:5). Obedience was united with worship. God answered them as intercessors for the people, who, though forgiven, were yet chastened (Ex 32:10, 34).

     8. he—Jehovah "said," that is, thought, in choosing them as His covenant-people; so "said" (Ps 95:10). Not that God was ignorant that the Jews would not keep faith with Him; but God is here said, according to human modes of thought to say within Himself what He might naturally have expected, as the result of His goodness to the Jews; thus the enormity of their unnatural perversity is the more vividly set forth.

     9. he was afflicted—English Version reads the Hebrew as the Keri (Margin), does, "There was affliction to Him." But the Chetib (text) reads, "There was no affliction" (the change in Hebrew being only of one letter); that is, "In all their affliction there was no (utterly overwhelming) affliction" [GESENIUS]; or, for "Hardly had an affliction befallen them, when the angel of His presence saved them" [MAURER]; or, as best suits the parallelism, "In all their straits there was no straitness in His goodness to them" [HOUBIGANT], (Jud 10:16; Mic 2:7; 2Co 6:12).
