(18) In the heavens.--Literally, in the vault. The Hebrew, galgal, from g?lal, "to roll," has the same derivation as "vault" (volutum, from volvo). It is strange that this rendering, which so well suits the parallelism, should have been set aside by modern scholars in favour of "whirlwind" or "rolling chariot wheels." The LXX. and Vulg. have "wheel," but possibly with reference to the apparent revolution of the sky. The word, where it occurs in Isaiah 17:13, means something rolled by the whirlwind, not the whirlwind itself.

Verse 18. - The voice of thy thunder was in the heavens; rather, in the whirlwind (Kay, Cheyne, Revised Version). A storm of wind usually accompanies thunder and lightning. This the author, with poetical exaggeration, heightens into a "whirlwind" (comp. Psalm 83:13; Isaiah 17:13). The lightnings lightened the world. More hyperbole. Not only did they "go abroad" (ver. 17), darting hither and thither, but their intense brightness illuminated the whole earth. The earth trembled and shook. Through the reverberation of air, the earth seems to shake in a heavy thunderstorm.

77:11-20 The remembrance of the works of God, will be a powerful remedy against distrust of his promise and goodness; for he is God, and changes not. God's way is in the sanctuary. We are sure that God is holy in all his works. God's ways are like the deep waters, which cannot be fathomed; like the way of a ship, which cannot be tracked. God brought Israel out of Egypt. This was typical of the great redemption to be wrought out in the fulness of time, both by price and power. If we have harboured doubtful thoughts, we should, without delay, turn our minds to meditate on that God, who spared not his own Son, but delivered him up for us all, that with him, he might freely give us all things.The voice of thy thunder was in the heaven,.... Thunder is the voice of God, Job 37:5 this is heard in "the orb" (b), or the air, so called, because spherical; the Targum is

"the voice of thy thunder was heard in the wheel;''

so the word here used sometimes signifies; so Ezekiel 10:13, and is so rendered here by some (c); some think this refers to the wheels of the chariots of the Egyptians, which were taken off, it may be by the force of thunder and lightning, so that they drove on heavily, Exodus 14:25,

the lightnings lightened the world; not only that part of the world where the Israelites and Egyptians were, but the whole world; for lightning comes out of the east, and shines to the west, Matthew 24:27, this was in the night, and a very dark night it was, as Josephus (d) affirms; see Psalm 97:4,

the earth trembled and shook; there was an earthquake at the same time; unless this is to be understood of the panic which the inhabitants of the earth were put into on hearing of this wonderful event, Joshua 2:9.
