But the LORD said unto Samuel, Look not on his countenance, or on the height of his stature; because I have refused him: for the LORD seeth not as man seeth; for man looketh on the outward appearance, but the LORD looketh on the heart.
And thou, Solomon my son, know thou the God of thy father, and serve him with a perfect heart and with a willing mind: for the LORD searcheth all hearts, and understandeth all the imaginations of the thoughts: if thou seek him, he will be found of thee; but if thou forsake him, he will cast thee off for ever.
For the work of a man shall he render unto him, and cause every man to find according to his ways.
My defence is of God, which saveth the upright in heart.
The fining pot is for silver, and the furnace for gold: but the LORD trieth the hearts.
But, O LORD of hosts, that judgest righteously, that triest the reins and the heart, let me see thy vengeance on them: for unto thee have I revealed my cause.
Great in counsel, and mighty in work: for thine eyes are open upon all the ways of the sons of men: to give every one according to his ways, and according to the fruit of his doings:
Who will render to every man according to his deeds:
And he that searcheth the hearts knoweth what is the mind of the Spirit, because he maketh intercession for the saints according to the will of God.
And I will kill her children with death; and all the churches shall know that I am he which searcheth the reins and hearts: and I will give unto every one of you according to your works.
