Too Wonderful

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 afar.
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,
    behold, O Lord, you know it altogether.
5 You hem me in, behind and before,
    and lay your hand upon me.
6 Such knowledge is too wonderful for me;
    it is high; I cannot attain it.

Ps 139: 1-6
