1O Lord, you have searched me and you know me. 2 You know when I sit and when I rise; you perceive my thoughts from afar. 3 You discern my going out and my lying down; you are familiar with all my ways. 4 Before a word is on my tongue you know it completely, O Lord. 5 You hem me in--behind and before; you have laid your hand upon me. 6 Such knowledge is too wonderful for me, too lofty for me to attain.
