You know when I sit down and when I rise up; you discern my thoughts from afar.
Psalm 139:2-6
You search out my path and my lying down and are acquainted with all my ways.
Even before a word is on my tongue, behold, O Lord, you know it altogether.
You hem me in, behind and before, and lay your hand upon me.
Such knowledge is too wonderful for me; it is high; I cannot attain it.
When you wish to do something evil, you retire from the public into your house where no enemy may see you; from those places of your house which are open and visible to the eyes of men you remove yourself into your room; even in your room you fear some witness from another quarter; you retire into your heart, there you meditate: He is more inward than your heart. Wherever, therefore, you shall have fled, there He is.
Herman Bavinck
