O Lord, You have searched me and known me.
You know when I sit down and when I rise up;
You understand my thought from afar.
You scrutinize my path and my lying down,
And are intimately acquainted with all my ways.
Even before there is a word on my tongue,
Behold, 
O Lord, You know it all.
You have enclosed me behind and before,
And laid Your hand upon me.

Psalm 139: 1-5 NASB95
