mountain, which was to prevent the people form ascending or touching it. Any one who touched it (קצהוּ, “its end,” i.e., the outermost or lowest part of the mountain) was to be put to death, whether man or beast. “No hand shall touch him” (the individual who passed the barrier and touched the mountain), i.e., no one was to follow him within the appointed boundaries, but he was to be killed from a distance either by stones or darts. (יּיּרה for יוּרה, see Gesenius, §69.) Not till “the drawing out of the trumpet blast,” or, as Luther renders it, “only when it sounded long,” could they ascend the mountain (Exo 19:13). היּבל, from יבל to stream violently with noise, is synonymous with היּבל קרן (Jos 6:5), and was really the same thing as the שׁופר, i.e., a long wind instrument shaped like a horn. היּבל משׁך is to draw the horn, i.e., to blow the horn with tones long drawn out. This was done either to give a signal to summon the people to war (Jdg 3:27; Jdg 6:34), or to call them to battle (Jdg 7:18; Job 39:24-25, etc.), or for other public proclamations. No one (this is the idea) was to ascend the mountain on pain of death, or even to touch its outermost edge; but when the horn was blown with a long blast, and the signal to approach was given thereby, then they might ascend it (see Exo 19:21), - of course not 600,000 men, which would have been physically impossible, but the people in the persons of their representatives the elders. בּהר עלות signifies to go up the mountain in Exo 19:13 as well as in Exo 19:12, and not merely to come to the foot of the mountain (see Deu 5:5).
verses 16-25
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
