Psalms 139:1

Psalms 139:1. O LORD, thou hast searched me, and known me.

It is true that God knows everything, but that is not what David says here. He makes a personal application of the universal truth: "O Lord, thou hast searched me, and known me." He does not talk about God’s knowledge of other men, but he speaks to God concerning himself: "O Lord, thou hast searched me, and known me ;" - "thou hast searched me as if thou wert looking for contraband goods. Thou hast ransacked me, thou hast gone down into my very heart, and hast spread out every secret part of my being: ‘Thou hast searched me, and known me.’"

"Lord, thou hast seareh’d and seen me through,

Thine eye commands with piercing view

My rising and my resting hours,

My heart and flesh, with all their powers."
