1 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 far away. 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, O Lord, you know it completely. 5 You hem me in, behind and before, and lay your hand upon me. 6 Such knowledge is too wonderful for me; it is so high that I cannot attain it.
