The earth shook - See Exodus 19:16-18.

The heavens also dropped at the presence of God - That is, dropped down rain and food. The idea is that the very heavens seemed to be shaken or convulsed, so that rain and food were shaken down - as ripe fruit falls from a tree that is shaken. Compare the notes at Isaiah 34:4. So also, Isaiah 64:1-3. The meaning is not that the heavens themselves dropped down, but that they dropped or distilled rain and food.

Even Sinai itself was moved - This was true; but this does not seem to be the idea intended here, for the words "even" and "was moved" are not in the original. The Hebrew is, literally, "This Sinai;" meaning probably" this was at Sinai," or, "this took place at Sinai." The correct translation perhaps would be, "The heavens distilled rain at the presence of God, this at Sinai, at the presence of God."

At the presence of God, the God of Israel - The whole region seemed to be moved and awed at the presence of God, or when he came down to visit his people. The earth and the heavens, all seemed to be in commotion.

The earth shook,.... Not only about Sinai, but in other places; see Psalm 114:1. It may also design the dread and trembling of the inhabitants of the earth, when they heard of the wonderful things God did for his people, Exodus 15:14;

the heavens also dropped at the presence of God; the Targum supplies, dew; to which may be added, quails and manna: though it rather seems to design a large shower of rain, which followed the lightning and thunder, when the law was given;

even Sinai itself was moved at the presence of God, the God of Israel: it is said to quake greatly, Exodus 19:18. The words of this verse and Psalm 68:7 seem to be borrowed out of the song of Deborah, Judges 5:4. Like effects followed the promulgation of the Gospel, even a shaking of the heavens and of the earth as an emblem of the removing of the ceremonial rites and Mosaic ordinances. Let it be observed, that Christ, who went before the Israelites in the wilderness, and whom they tempted and rebelled against, is called the God of Israel.

The earth shook, the heavens also dropped at the presence of God: even Sinai itself was moved at the presence of God, the God of Israel.

68:8 Dropped - Poured down great showers, which accompanied those mighty thunders.

8. even Sinai itself-literally, "that Sinai," as in Jud 5:5.

68:7-14 Fresh mercies should put us in mind of former mercies. If God bring his people into a wilderness, he will be sure to go before them in it, and to bring them out of it. He provided for them, both in the wilderness and in Canaan. The daily manna seems here meant. And it looks to the spiritual provision for God's Israel. The Spirit of grace and the gospel of grace are the plentiful rain, with which God confirms his inheritance, and from which their fruit is found. Christ shall come as showers that water the earth. The account of Israel's victories is to be applied to the victories over death and hell, by the exalted Redeemer, for those that are his. Israel in Egypt among the kilns appeared wretched, but possessed of Canaan, during the reigns of David and Solomon, appeared glorious. Thus the slaves of Satan, when converted to Christ, when justified and sanctified by him, look honourable. When they reach heaven, all remains of their sinful state disappear, they shall be as the wings of the dove, covered with silver, and her feathers as gold. Full salvation will render those white as snow, who were vile and loathsome through the guilt and defilement of sin.
