The Omniscience of God

Psalm 139:1–6

Search Me, O God, and Know My Heart

To the choirmaster. A Psalm of David.

1   O LORD, you have searched me and known me!
2   You know when I sit down and when I rise up;
    you discern my thoughts from afar.
3   You search out my path and my lying down
    and are acquainted with all my ways.
4   Even before a word is on my tongue,
    behold, O LORD, you know it altogether.
5   You hem me in, behind and before,
    and lay your hand upon me.
6   Such knowledge is too wonderful for me;
    it is high; I cannot attain it.

(ESV)
