John Gill's Exposition of the Whole Bible
Psalms 113:6
Who humbleth himself to behold the things that are in heaven, and in the earth. The persons the highest heavens, the angels whom he upholds in their beings, and admits into his presence; who always behold his face, and he beholds them, delights in their persons, and accepts their services; which, though pure and perfect, it is a condescension in him to do, since they are but creature services, and chargeable with folly and weakness; and who themselves are as nothing in comparison of him, and veil their faces before him; Job 4:18, also glorified saints are continually in his view, and favoured with intimate communion with him: and he humbles himself to look lower than this, and behold the things in the starry heavens, the sun, and moon, and stars; whom he preserves in their being, directs their courses, and continues their influence; brings out their host by number, calls them by their names, and because of his power not one fails: he looks lower still, and beholds the things in the airy heavens; there is not a meteor or cloud that flies, or a wind that blows, but he observes, guides, and directs it; nor a bird in the air but his eye is on it; he feeds the fowls of the air, and not so much as a sparrow falls to the ground without his knowledge and will: and he also humbles himself to behold persons and things on earth, even every beast of the forest, the cattle on a thousand hills, all the fowls of the mountains, and the wild beasts of the field; and their eyes are on him, and he gives them their food in due season; he looks down from heaven and beholds all the children of men, and is the Saviour of them in a providential way; in an especial manner his eye, both of providence and grace, is on his own people, whom he beholds in Christ as fair and comely: and rejoices over them to do them good; and he has respect to their services for his sake, and condescends to dwell on earth with them. This may also be applied to Christ, who humbled himself to look upon the angels in heaven, and take them under his care and protection, be the head of them, and confirm them in that estate in which they were created: and who from all eternity vouchsafed to look with delight upon the sons of men, rejoicing in the habitable parts of the earth, where he knew they would dwell; and in the fulness of time he humbled himself to come down on earth in human nature and dwell among men, and become very man in that nature; made himself of no reputation, and humbled himself so as to become obedient to death, the death of the cross, and be made sin and a curse for his people. This was an humiliation indeed!
