Psalm 139:1-24 (ESV)

(1) To the choirmaster. A Psalm of David. O LORD, you have searched me and known me! (2) You know when I sit down and when I rise up; you discern my thoughts from afar. (3) You search out my path and my lying down and are acquainted with all my ways. (4) Even before a word is on my tongue, behold, O LORD, you know it altogether. (5) You hem me in, behind and before, and lay your hand upon me. (6) Such knowledge is too wonderful for me; it is high; I cannot attain it.
