2. Mose 19:10

God then commanded Moses to prepare the people for His appearing or speaking to them: (1) by their sanctification, through the washing of the body and clothes (see Gen 35:2), and abstinence from conjugal intercourse (Exo 19:15) on account of the defilement connected therewith (Lev 15:18); and (2) by setting bounds round the people, that they might not ascend or touch the mountain. The hedging or bounding (הגבּיל) of the people is spoken of in Exo 19:23 as setting bounds about the mountain, and consisted therefore in the erection of a barrier round the 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 app…

This chapter introduces the solemnity of the giving of the law upon mount Sinai, which was one of the most striking appearances of the divine glory that ever was in this lower world. We have here, I. The circumstances of time and place (Exo 19:1, Exo 19:2). II. The covenant between God and Israel settled in general. The gracious proposal God made to them (Exo 19:3-6), and their consent to the proposal (Exo 19:7, Exo 19:8). III. Notice given three days before of God's design to give the law out of a thick cloud (Exo 19:9). Orders given to prepare the people to receive the law (Exo 19:10-13), and care taken to execute those orders (Exo 19:14, Exo 19:15). IV. A terrible appearance of God's glory upon mount Sinai (Exo 19:16-20). V. Silence proclaimed, and strict charges given to the people to observe decorum while God spoke to them (Exo 19:21, etc.).

19:10-15 In the second phase of preparation, the people received commands that would prepare them to receive God’s covenant. They were to wash their clothing (19:10, 14) because God is pure. They were to prepare a boundary all around the mountain (19:12-13) and be careful not to cross it because God is holy. They were to abstain from having sexual intercourse (19:15) because God is not a sexual being, and his blessings are not produced through sexual activity. Things that are natural and right under ordinary circumstances were to be set aside for the extraordinary purpose of concentrating on the Lord, the King who was about to appear before the people. Only their compliance with the second of these commands is specifically reported (19:23), but it is safe to assume that they obeyed the other two as well since no negative response from the Lord is recorded. • Hebrews 12:18-22 contrasts this experience at Mount Sinai with the believer’s experience at Mount Zion, “the heavenly Jerusalem.”
