1391 To the choirmaster. A Psalm of David. O Lord, thou hast searched me and known me! 2 Thou knowest when I sit down and when I rise up; thou discernest my thoughts from afar. 3 Thou searchest out my path and my lying down, and art acquainted with all my ways. 4 Even before a word is on my tongue, lo, O Lord, thou knowest it altogether. 5 Thou dost beset me behind and before, and layest thy hand upon me. 6 Such knowledge is too wonderful for me; it is high, I cannot attain it.
7 Whither shall I go from thy Spirit? Or whither shall I flee from thy presence? 8 If I ascend to heaven, thou art there! If I make my bed in Sheol, thou art there! 9 If I take the wings of the morning and dwell in the uttermost parts of the sea, 10 even there thy hand shall lead me, and thy right hand shall hold me. 11 If I say, "Let only darkness cover me, and the light about me be night," 12 even the darkness is not dark to thee, the night is bright as the day; for darkness is as light with thee.
Matthew Henry's Commentary on Psalm 139:1-12
Commentary on Psalm 139:1-6
(Read Psalm 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 When I am withdrawn from all company, thou knowest what I have in my heart.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.
Commentary on Psalm 139:7-16
(Read Psalm 139:7-16)
We cannot see God, but he can see us. The psalmist did not desire to go from the Lord. Whither can I go? In the most distant corners of the world, in heaven, or in hell, I cannot go out of thy reach. No veil can hide us from God; not the thickest darkness. No disguise can save any person or action from being seen in the true light by him. Secret haunts of sin are as open before God as the most open villanies. On the other hand, the believer cannot be removed from the supporting, comforting presence of his Almighty Friend. Should the persecutor take his life, his soul will the sooner ascend to heaven. The grave cannot separate his body from the love of his Saviour, who will raise it a glorious body. No outward circumstances can separate him from his Lord. While in the path of duty, he may be happy in any situation, by the exercise of faith, hope, and prayer.
