Psalms 139:1-6 (NRSV:Catholic Edition)
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 is on my tongue,
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.
