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.

And thou shalt remember all the way which the LORD thy God led thee these forty years in the wilderness, to humble thee, and to prove thee, to know what was in thine heart, whether thou wouldest keep his commandments, or no.

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.

Oh let the wickedness of the wicked come to an end; but establish the just: for the righteous God trieth the hearts and reins.

Behold, thou desirest truth in the inward parts: and in the hidden part thou shalt make me to know wisdom.

All the ways of a man are clean in his own eyes; but the LORD weigheth the spirits.

Every way of a man is right in his own eyes: but the LORD pondereth the hearts.

I the LORD search the heart, I try the reins, even to give every man according to his ways, and according to the fruit of his doings.

For the word of God is quick, and powerful, and sharper than any twoedged sword, piercing even to the dividing asunder of soul and spirit, and of the joints and marrow, and is a discerner of the thoughts and intents of the heart.

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.

They that are of a froward heart are abomination to the LORD: but such as are upright in their way are his delight.

The sacrifice of the wicked is an abomination to the LORD: but the prayer of the upright is his delight.

The way of the wicked is an abomination unto the LORD: but he loveth him that followeth after righteousness.

Jesus saw Nathanael coming to him, and saith of him, Behold an Israelite indeed, in whom is no guile!

And herein do I exercise myself, to have always a conscience void of offence toward God, and toward men.

For our rejoicing is this, the testimony of our conscience, that in simplicity and godly sincerity, not with fleshly wisdom, but by the grace of God, we have had our conversation in the world, and more abundantly to you-ward.

Ye are witnesses, and God also, how holily and justly and unblameably we behaved ourselves among you that believe:

Then the people rejoiced, for that they offered willingly, because with perfect heart they offered willingly to the LORD: and David the king also rejoiced with great joy.

For we have great joy and consolation in thy love, because the bowels of the saints are refreshed by thee, brother.

Yea, brother, let me have joy of thee in the Lord: refresh my bowels in the Lord.
