1391 O Lord, you have knowledge of me, searching out all my secrets. 2 You have knowledge when I am seated and when I get up, you see my thoughts from far away. 3 You keep watch over my steps and my sleep, and have knowledge of all my ways. 4 For there is not a word on my tongue which is not clear to you, O Lord. 5 I am shut in by you on every side, and you have put your hand on me. 6 Such knowledge is a wonder greater than my powers; it is so high that I may not come near it.
7 Where may I go from your spirit? how may I go in flight from you? 8 If I go up to heaven, you are there: or if I make my bed in the underworld, you are there. 9 If I take the wings of the morning, and go to the farthest parts of the sea; 10 Even there will I be guided by your hand, and your right hand will keep me. 11 If I say, Only let me be covered by the dark, and the light about me be night; 12 Even the dark is not dark to you; the night is as bright as the day: for dark and light are the same to you. 13 My flesh was made by you, and my parts joined together in my mother's body. 14 I will give you praise, for I am strangely and delicately formed; your works are great wonders, and of this my soul is fully conscious. 15 My frame was not unseen by you when I was made secretly, and strangely formed in the lowest parts of the earth. 16 Your eyes saw my unformed substance; in your book all my days were recorded, even those which were purposed before they had come into being.
17 How dear are your thoughts to me, O God! how great is the number of them! 18 If I made up their number, it would be more than the grains of sand; when I am awake, I am still with you.

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 When I am withdrawn from all company, thou knowest what I have in my heart.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.
Commentary on Psalm 139:17-24
(Read Psalm 139:17-24)
God's counsels concerning us and our welfare are deep, such as cannot be known. We cannot think how many mercies we have received from him. It would help to keep us in the fear of the Lord all the day long, if, when we wake in the morning, our first thoughts were of him: and how shall we admire and bless our God for his precious salvation, when we awake in the world of glory! Surely we ought not to use our members and senses, which are so curiously fashioned, as instruments of unrighteousness unto sin. But our immortal and rational souls are a still more noble work and gift of God. Yet if it were not for his precious thoughts of love to us, our reason and our living for ever would, through our sins, prove the occasion of our eternal misery. How should we then delight to meditate on God's love to sinners in Jesus Christ, the sum of which exceeds all reckoning! Sin is hated, and sinners lamented, by all who fear the Lord. Yet while we shun them we should pray for them; with God their conversion and salvation are possible. As the Lord knows us thoroughly, and we are strangers to ourselves, we should earnestly desire and pray to be searched and proved by his word and Spirit. if there be any wicked way in me, let me see it; and do thou root it out of me. The way of godliness is pleasing to God, and profitable to us; and will end in everlasting life. It is the good old way. All the saints desire to be kept and led in this way, that they may not miss it, turn out of it, or tire in it.
