1 Samuel 16:7; 1 Chronicles 28:9; Psalm 139:23; Romans 8:27

But the Lord said to Samuel, bDo not look on his appearance or on the height of his stature, because I have rejected him. For the Lord sees not as man sees: man looks on the outward appearance, cbut the Lord looks on the heart.

David's Charge to Solomon

And you, Solomon my son, know the God of your father and serve him with a ywhole heart and with a willing mind, zfor the Lord searches all hearts and understands every plan and thought. aIf you seek him, he will be found by you, but if you forsake him, he will cast you off forever.

23  Search me, O God, and know my heart!

vTry me and know my thoughts!1

27 And dhe who searches hearts knows what is ethe mind of the Spirit, because1 the Spirit fintercedes for the saints gaccording to the will of God.
