He that planted the ear - He that made the ear. The word here used in the original is a participle. "Shall not he planting the ear;" that is, the "planter" of the ear. The idea seems to have been taken from the act of making a "hole" in the ground when we set out a plant - as if, in like manner, a "hole" had been made in the side of the head to insert the ear.
Shall he not hear? - He could not have created the faculty of hearing, without possessing it himself. Or, it is reasonable to suppose that he who has made man capable of hearing, must be able to hear himself. We have nothing in our nature which is not possessed in an infinitely higher measure by God.
He that formed the eye - This, too, is a participle: "He forming the eye;" that is, the Former of the eye. The word used here is frequently employed in reference to a "potter;" and the idea is that God has moulded or formed the eye as the potter fashions the clay. The more the eye is studied in its structure, the more deeply shall we be impressed with the wonderful skill and wisdom of God. See this beautifully illustrated in Paley's Natural Theology.
Shall he not see? - He that made the eye to see must himself be able to see. He must see all that the eye itself can see; he must see all that all eyes see; he must have the power of sight far beyond what there is in the mere organ which he has made.

He that planted the ear, shall he not hear? - This is allowed to be an unanswerable mode of argumentation. Whatever is found of excellence in the creature, must be derived from the Creator, and exist in him in the plenitude of infinite excellence. God, says St. Jerome, is all eye, because he sees all; he is all hand, because he does all things; he is all foot, for he is every where present. The psalmist does not say, He that planted the ear, hath he not an ear? He that formed the eye, hath he not eyes? No; but, Shall he not hear? Shall he not see! And why does he say so? To prevent the error of humanizing God, of attributing members or corporeal parts to the infinite Spirit. See Calmet.

He that (f) planted the ear, shall he not hear? he that formed the eye, shall he not see?
(f) He shows that it is impossible, but God should hear, see, and understand their wickedness.

He that planted the ear,.... In the human body, with so much art and skill, in so convenient a place, so capacious of receiving sounds, and fitted it with organs suited for such a purpose:
shall he not hear? the atheism spoke in the heart, in the actions and by the mouths of such blasphemers of him; the hard speeches spoken against his Son, his person and offices; and against his Spirit, his being, and operations; and against his people, the saints of the most High; in short, all those blasphemies and evil speakings of God, of his tabernacle, and those that dwell therein: it would be monstrous stupidity to imagine, that that God, that communicates a faculty of hearing to his creatures, should not hear himself; for none can give that which they have not:
he that formed the eye: in so curious a manner, with such exquisite parts; with such fine humours, nerves, and tunics; so adapted to receive all objects, and take the impress of them in so wonderful a manner:
shall he not see? all persons and things, all the ways and actions of men; certainly he must: clouds, rocks, and hills, are no obstruction to him; the darkness and the light are both alike to him; his eyes are everywhere, and all things are naked and open before him: it is the height of madness and folly to think that that God cannot see what men are doing here below, who has given to men eyes to see the heavens above, and all their host; and in this so small a compass to take in the sight of the largest mountains, as well as the most minute things: since the seeing eye, and the hearing ear, are both from the Lord, it may be most strongly concluded that he hears all that is said, and sees all that is done, against him and his people; see Proverbs 20:12. A Heathen (c) could say,
"truly there is a God, who hears and sees all that we do.''
(c) Plauti Capteivei, Acts. 2. Sc. 2. v. 63.

The evidence of God's providential government is found in His creative power and omniscience, which also assure us that He can punish the wicked in regard to all their vain purposes.

Planted - The word is emphatical, signifying the excellent structure of the ear, or the several organs belonging to the sense of hearing. Formed - By which word he intimates the accurate and curious workmanship of the eye.
