He holdeth back the face of his throne - That is, he does not exhibit it - he covers it with clouds. The idea seems to be, that God sometimes comes forth and manifests himself to mankind, but that he comes encompassed with clouds, so that his throne cannot be seen. So in Psalm 18:11, "He made darkness his secret place, his pavilion round about him were dark waters and thick clouds of the skies." God is often represented as encompassed with clouds, or as accompanied with tempests.
And spreadeth his cloud upon it - That is, so that it cannot be seen. There is much poetic beauty in this image. It is, that the clouds are made to conceal the splendor of the throne of God from the sight of man, and that all their sublimity and grandeur, as they roll on one another, and all their beauty when painted with so many colors in the evening, are designed to hide that throne from mortal eyes. No one sees God; and though it is manifest that he is every where employed, and that he comes forth with amazing grandeur in the works of creation and providence, yet he is himself invisible.

He holdeth back the face of his throne - Though all these are most elegant effects of an omniscient and almighty power, yet the great Agent is not personally discoverable; he dwelleth in light unapproachable, and in mercy hides himself from the view of his creatures. The words, however may refer to those obscurations of the face of heaven, and the hiding of the body of the sun, when the atmosphere is laden with dense vapours, and the rain begins to be poured down on the earth.

He holdeth back the face of his throne,.... His throne is the heaven of heavens; the face of it, or what is before it, is the starry and airy heavens; this face of his throne is sometimes held back, or covered with clouds, that so his throne is so far from being visible, that even the face of it, or the outside or external appearance of it, is not to be seen, as follows:
and spreadeth his cloud upon it; and both he and his throne are invisible; clouds and darkness are round about him, and his pavilion round about are dark waters, and thick clouds of the skies, Psalm 18:11; and even the light in which he dwells, and with which he clothes himself, is impervious to us, and is so dazzling, that itself covers and keeps back himself and throne from being seen by mortals. The Targum suggests, that what is here said to be done is done that the angels may not see it; but these always stand before the throne of God, and always behold the face of God himself.

Rather, He encompasseth or closeth. God makes the clouds a veil to screen the glory not only of His person, but even of the exterior of His throne from profane eyes. His agency is everywhere, yet He Himself is invisible (Psalm 18:11; Psalm 104:3).

Holdeth - From our view, that his glory may not dazzle our sight; he covereth it with a cloud. Throne - The heaven of heavens, where he dwelleth.
