Who hath ascended up into heaven, or descended? who hath gathered the wind in his fists? who hath bound the waters in a garment? who hath established all the ends of the earth? what is his name, and what is his son's name, if thou canst tell?
Nor is it any wonder that I have not the knowledge of the Holy; for:
Who hath ascended up into heaven, or descended? - so as to understand what is being done there, so as to tell mortals what he hath seen. We Christians can tell of such a one (John 3:13). Though we have not ascended into heaven, or descended into the depth; still, in all that is vital to know, we have 'the word nigh' to us (Romans 10:6-8; Deuteronomy 30:12-13.)
Who hath gathered the wind in his fists? - firmly grasped.
Who hath bound the waters in a garment? - (Isaiah 40:12.) As Israel bound the dough in their clothes (Exodus 12:34).
Who hath established all the ends of the earth? - the boundaries of land and sea, and of the several distinct kingdoms. None except God. Therefore He alone knoweth thoroughly the deep mysteries of the universe.
What (is) his name, and what (is) his son's name? The Hebrews designate a man by not only his own name, but by his relations. In allusion to this usage, but with a designed reference to the mystery of the everlasting generation of the Son of God, the Spirit puts this question into Agur's mouth, Can you tell His name (i:e., His nature) and His Son's? (Proverbs 8:22-31.) None can; therefore, naturally, none can "have the knowledge of the Holy" One (Proverbs 30:3; Matthew 11:27; Matthew 16:17). The name of God, and that of His Son, are here joined, as both alike ineffable and incomprehensible. Co-existence and omnipresence (by the ascent to heaven and descent), creative and all-sustaining omnipotence are ascribed to both. The Son is represented as distinct from the Father in personality, yet one in essence and operation.
