Note, 1. God is the God of nature, and all the powers and faculties of nature are derived from him and depend upon him, and therefore are to be employed for him. It was he that formed the eye and planted the ear (Psa 94:9), and the structure of both is admirable; and it is he that preserves to us the use of both; to his providence we owe it that our eyes are seeing eyes and our ears hearing ears. Hearing and seeing are the learning senses, and must particularly own God's goodness in them. 2. God is the God of grace. It is he that gives the ear that hears God's voice, they eye that sees his beauty, for it is he that opens the understanding.

The hearing ear, and the seeing eye,.... There may be an ear that hears not, and an eye that seeth not, and which men may make; the painter can paint an ear and an eye, and a carver can carve both; but they are ears that hear not, and eyes that see not, Psa 115:5; but such as can hear and see are of the Lord's own make;

the Lord hath made even both of them; they are the effects of his wisdom, power, and goodness; see Exo 4:11; they are both senses of excellent use and service; great mercies and blessings of life, for which men should be abundantly thankful, and pray for the continuance of, and make use of to the best purposes; they are means of conveying much knowledge to the mind, and by which it may be cultivated and improved in it. The words may be considered in a figurative as well as a literal sense. Some by "the seeing eye" understand the civil magistrate, who is that to the body politic as the eyes are to the natural body, eminent in it, overlook it, watch and provide for its good, and against its hurt; see Num 10:31; and by "the hearing ear" the obedient subject, that hearkens to the laws and directions of his governors, and cheerfully obeys them, and both these are of the Lord's making; civil magistracy is his ordinance, and civil magistrates are ordained by him; and from him they have their qualifications fitting them for their office; and it is owing to the overruling providence of God on the hearts of men that they are inclined to yield subjection to them. Others think that by the "seeing eye" are meant the ministers of the word, who are set in the highest place in the church; whose business it is to inspect, take the oversight of, and watch the souls of men; to pry and search into the truths of the Gospel, and show them to others: and by the "hearing ear" the hearers of the word, that receive it readily in the love of it, and heartily obey it. I am rather of opinion that one and the same sort of persons are intended; converted ones, who have the "hearing ear", who try what they hear by the word of God; understand what they hear, know it experimentally; can distinguish truth from error, approve and love the Gospel, receive it with all gladness and readiness, with eagerness and pleasure; keep it when they have it, and practise what they hear, and bring forth fruit to the glory of God: this they have not of themselves, being naturally averse to and dull of hearing, and even stop their ears to the truth; but it comes by the word, and is the Lord's work, and owing to his mighty power, who opens their ears, gives them new ears, which they have in regeneration; when they hear spiritually, profitably, pleasantly, comfortably, and to their great astonishment: these also have the "seeing eye", a sight of themselves, their sinful and lost estate; of the plague of their own hearts, their want of righteousness, and impotence to do anything that is good; a sight of Christ, of the loveliness of his person, of the fulness of his grace, of their need of him, and of his suitableness as a Saviour and Redeemer; and this is not of themselves, who are dark and darkness itself, but they are made light in the Lord; he opens their eyes by his spirit and by means of his word, which is a work of almighty power.

Hence, of course, God will know all you do (Psa 94:9).
