Psalm 139 The Inescapable God - To the leader. Of David. A Psalm. O LORD, you have searched me and known me. You know when I sit down and when I rise up; you discern my thoughts from far away. You search out my path and my lying down, and are acquainted with all my ways. Even before a word is on my tongue, O LORD, you know it completely. You hem me in, behind and before, and lay your hand upon me.
