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 afar.
You search out my path and my lying down
and are acquainted with all my ways.
Even before a word is on my tongue,
behold, O LORD, you know it altogether.
You hem me in, behind and before,
and lay your hand upon me.
Such knowledge is too wonderful for me;
it is high; I cannot attain it.
