"O Lord, you have seached me
and you know me.
You know when I sit and when I rise,
you perceive my thoughts from afar.
You discern my going out and my lying down;
you are familiar with all my ways.
Before a word is on my tongue
you know it completely, O Lord.
You hem me in -- behind and before;
you have laid your hand upon me.
Such knowledge is too wonderful for me,
too lofty for me to atain."
Psalm 139 : 1 - 6 NIV
