To him that rideth upon the heavens of heavens - The highest heavens. The heaven of heaven would properly mean the heaven above that which is heaven to us; that is, the heaven above the sky. This is represented as the special dwelling-place of God. The Jews were accustomed to speak of three heavens:
(a) The aerial heaven, or the region above us, where the birds fly, and the winds blow;
(b) the starry heavens, or the firmament in which the stars are fixed; and
(c) the heaven above all, the abode of God and of angels.
The word "rideth" here means that he appears there as a conqueror, or that he moves in majesty and glory. See the notes at Psalm 18:10.
Which were of old - The words "of old" refer here to the heavens, and denote their antiquity. He rides upon those ancient heavens. He occupies a position above those ancient works of his power.
Lo, he doth send out his voice - Margin, as in Hebrew, "give." The reference is to thunder. The design of this is to increase the impression of his majesty and power.
And that a mighty voice - See the notes at Psalm 29:3.

Rideth upon the heavens - He who manages the heavens, directing their course and influence, he formed every orb, ascertained its motion, proportioned its solid contents to the orbit in which it was to revolve, and the other bodies which belong to the same system. As an able and skillful rider manages his horse, so does God the sun, moon, planets, and all the hosts of heaven.
He doth send out his voice - At his word of command they run, shed, or reflect their light; and without the smallest deviations obey his will.
Mighty voice - He thunders in the heavens, and men tremble before him.

To him that rideth upon the heavens of heavens, [which were] of old; lo, he doth send out his (c) voice, [and that] a mighty voice.
(c) By his terrible thunders he will make himself be known as the God of all the world.

To him that rideth upon the heaven of heavens, which were of old,.... Or "eastward" (q); the first, second, and third heavens, which were created from the beginning of time by Christ himself, Psalm 102:25 compared with Hebrews 1:10. These he rode upon when he ascended on high, even far above all heavens, as the apostle says, Ephesians 4:10; and so above the heaven of heavens, when he was made higher than they, and both Lord and Christ; and placed his throne in them, and from thence exercises his government over the whole world: and it may be observed, that it was from Mount Olivet, which was to the east of Jerusalem, that Christ ascended, and so to the eastern part of the heavens, Acts 1:12; see Revelation 7:2;
lo, he doth send out his voice; which is his Gospel, for that is the voice of Christ; which he utters by his ministers, and which his sheep, his people, hearken unto, and can distinguish from the voice of a stranger. This is a voice of love, grace, and mercy; it speaks of righteousness, peace, pardon, and salvation by him, and is very joyful and comfortable to hear. This he sent out by his apostles into all the earth, after his ascension to heaven; and which he has been, more or less, sending out in one place or another, by his ministers, ever since; and in the latter day will send it out more clearly, fully, and largely, by a set of ministers he will raise up for that purpose;
and that a mighty voice; or, "a voice of strength" (r); a strong and powerful voice, such as the Gospel is, when accompanied with the power and Spirit of God. It is a soul shaking and awakening voice; it is an heartmelting and an heartbreaking one; it is a quickening and an enlightening voice; it quickens dead sinners, gives life unto them, and the entrance of it gives light to dark minds: it is a soul charming and alluring one; it draws to Christ, engages the affections to him, and fills with unspeakable delight and pleasure. The Targum interprets this of the voice of the spirit of prophecy; Aben Ezra understands this voice as saying what follows.
(q) "ab oriente", Pagninus; "ad orientem", V. L. so Sept. Eth. Syr. Arab. (r) "vocem fortitudinis", Pagninus, Montanus.

Heavens - The highest heavens; dwelling there in infinite glory, and from thence looking down upon all the inhabitants of the earth, and ruling them by his almighty power. Of old - From the beginning of the world; whereas the ark was only some hundred years old. A voice - His gospel, published by Christ and his apostles, assisted by the Holy Spirit sent from heaven; which might well be called God's voice, and that a mighty voice, because it produced such great and wonderful effects.
