(1) Searched . . .--Comp. Psalm 44:21, "shall not God search this out." The word is used of mining operations, Job 28:3; of exploring a country, Judges 18:2.

Verse 1. - O Lord, thou hast searched me; rather, hast searched me out; i.e. examined into all my thoughts and feelings (comp. Psalm 17:3). And known me; i.e. arrived at a full knowledge of my spiritual condition.

139:1-6 God has perfect knowledge of us, and all our thoughts and actions are open before him. It is more profitable to meditate on Divine truths, applying them to our own cases, and with hearts lifted to God in prayer, than with a curious or disputing frame of mind. That God knows all things, is omniscient; that he is every where, is omnipresent; are truths acknowledged by all, yet they are seldom rightly believed in by mankind. God takes strict notice of every step we take, every right step and every by step. He knows what rule we walk by, what end we walk toward, what company we walk with. When I am withdrawn from all company, thou knowest what I have in my heart. There is not a vain word, not a good word, but thou knowest from what thought it came, and with what design it was uttered. Wherever we are, we are under the eye and hand of God. We cannot by searching find how God searches us out; nor do we know how we are known. Such thoughts should restrain us from sin.O Lord, thou hast searched me, and known me. The omniscience of God reaches to all persons and things; but the psalmist only takes notice of it as respecting himself. God knows all men in general, and whatever belongs to them; he knows his own people in a special manner; and he knows their particular persons, as David and others: and this knowledge of God is considered after the manner of men, as if it was the fruit of search, to denote the exquisiteness of it; as a judge searches out a cause, a physician the nature of a disease, a philosopher the reason of things; who many times, after all their inquiries, fail in their knowledge; but the Lord never does: his elect lie in the ruins of the fall, and among the men of the world; he searches them out and finds them; for be knows where they are, and the time of finding them, and can distinguish them in a crowd of men from others, and notwithstanding the sad case they are in, and separates them from them; and he searches into them, into their most inward part, and knows them infinitely better than their nearest relations, friends and acquaintance do; he knows that of them and in them, which none but they themselves know; their thoughts, and the sin that dwells in them: yea, he knows more of them and in them than they themselves, Jeremiah 17:9. And he knows them after another manner than he does other men: there are some whom in a sense he knows not; but these he knows, as he did David, so as to approve of, love and delight in, Matthew 7:23.
