2. O LORD, you have searched me and you know me. 2You know when I sit and when I rise;        you perceive my thoughts from afar. 3You discern my going out and my lying down;        you are familiar with all my ways. 4Before a word is on my tongue        you know it completely, O LORD. 5You hem me in—behind and before;        you have laid your hand upon me. 6Such knowledge is too wonderful for me,        too lofty for me to attain. David, King of Israel, ≈ 1000 BC
