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