Matthew Henry's Complete Bible Commentary

Verse 3

The great truths of divinity are of great use to enforce the precepts of morality, and none more than this—That the eye of God is always upon the children of men. 1. An eye to discern all, not only from which nothing can be concealed, but by which every thing is actually inspected, and nothing overlooked or looked slightly upon: The eyes of the Lord are in every place; for he not only sees all from on high (Psalms 33:13), but he is every where present. Angels are full of eyes (Revelation 4:8), but God is all eye. It denotes not only his omniscience, that he sees all, but his universal providence, that he upholds and governs all. Secret sins, services, and sorrows, are under his eye. 2. An eye to distinguish both persons and actions. He beholds the evil and the good, is displeased with the evil and approves of the good, and will judge men according to the sight of his eyes, Psalms 1:6, 11:4. The wicked shall not go unpunished, nor the righteous unrewarded, for God has his eye upon both and knows their true character; this speaks as much comfort to saints as terror to sinners. MHBCC 644.3
