Psalm 139:1-6 (NIV)
1O 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.
Jeremiah 17:10 (NIV)
"I the Lord search the heart and examine the mind, to reward a man according to his conduct, according to what his deeds deserve."
