2. Mose 19:16

After these preparations, on the morning of the third day (from the issuing of this divine command), Jehovah came down upon the top of Mount Sinai (Exo 19:20), manifesting His glory in fire as the mighty, jealous God, in the midst of thunders (קלת) and lightnings, so that the mountain burned with fire (Deu 4:11; Deu 5:20), and the smoke of the burning mountain ascended as the smoke (עשׁן for עשׁן), and the whole mountain trembled (Exo 19:18), at the same time veiling in a thick cloud the fire of His wrath and jealousy, by which the unholy are consumed. Thunder and lightning bursting forth from the thick cloud, and fire with smoke, were the elementary substrata, which rendered the glory of the divine nature visible to men, though in such a way that the eye of mortals beheld no form of the spiritual and invisible Deity. These natural phenomena were accompanied by a loud trumpet blast, which "blew long and waxed louder and louder" (Exo 19:16 and Exo 19:19; see Gen 8:3), and was, as it were, the herald's call, announcing to the people the appearance of the Lord, and summoning them to assemble before Him and listen to His words, as they sounded forth from the fire and cloudy darkness. The blast (קול) of the shophar (Exo 19:19), i.e., the σάλπιγξ Θεοῦ, the trump of God, such a trumpet as is used in the service of God (in heaven, Th1 4:16; see Winer's Grammar), is not "the voice of Jehovah," but a sound resembling a trumpet blast. Whether this sound was produced by natural means, or, as some of the earlier commentators supposed, by angels, of whom myriads surrounded Jehovah when He came down upon Sinai (Deu 33:2), it is impossible to decide. At this alarming phenomenon, "all the people that was in the camp trembled" (Exo 19:16). For according to Exo 20:20 (17), it was intend…

Now, at length, comes that memorable day, that terrible day of the Lord, that day of judgment, in which Israel heard the voice of the Lord God speaking to them out of the midst of the fire, and lived, Deu 4:33. Never was there such a sermon preached, before nor since, as this which was here preached to the church in the wilderness. For, I. The preacher was God himself (Exo 19:18): The Lord descended in fire, and (Exo 19:20), The Lord came down upon mount Sinai. The shechinah, or glory of the Lord, appeared in the sight of all the people; he shone forth from mount Paran with ten thousands of his saints (Deu 33:2), that is, attended, as the divine Majesty always is, by a multitude of the holy angels, who were both to grace the solemnity and to assist at it. Hence the law is said to be given by the disposition of angels, Act 7:53. II. The pulpit (or throne rather) was mount Sinai, hung with a thick cloud (Exo 19:16), covered with smoke (Exo 19:18), and made to quake greatly. Now it was that the earth trembled at the presence of the Lord, and the mountains skipped like rams (Psa 114:4, Psa 114:7), that Sinai itself, though rough and rocky, melted from before the Lord God of Israel, Jdg 5:5. Now it was that the mountains saw him, and trembled (Hab 3:10), and were witnesses against a hard-hearted unmoved people, whom nothing would influence. III. The congregation was called together by the sound of a trumpet, exceedingly loud (Exo 19:16), and waxing louder and louder, Exo 19:19. This was done by the ministry of the angels, and we read of trumpets sounded by angels, Rev 8:6. It was the sound of the trumpet that made all the people tremble, as those who knew their own guilt, and who had reason to expect that the sound of this trumpet was to them the alarm of war. IV. Moses brou…

19:16-25 The final phase of preparation involved phenomena that moved the people toward acceptance of the covenant. Some of the experiences were visual: lightning and a cloud (19:16), smoke and fire (19:18). The people also heard thunder, a ram’s horn, and the voice of God (19:16, 19), and the whole mountain shook violently (19:18). In the Bible, such phenomena are often associated with a theophany, which is a visible manifestation of God’s holy presence.
