As for you, my son Solomon, know the God of your father, and serve Him with a perfect heart and with a willing mind; for Jehovah searches all hearts and understands all the intent of the thoughts. If you seek Him, He will be found by you; but if you forsake Him, He will cast you off forever.

And you shall remember that Jehovah your God has led you all the way these forty years in the wilderness, to humble you and test you, to know what was in your heart, whether you would keep His commandments or not.

But Jehovah said to Samuel, Do not look at his appearance nor at the height of his stature, because I have refused him. For man does not see as He sees; for man looks at the outward appearance, but Jehovah looks at the heart.

O let the wickedness of the wicked come to an end, but establish the just. For the righteous God tries the hearts and minds.

Behold, You desire truth in the inward parts; and in the hidden part You shall make me to know wisdom.

All the ways of a man are pure in his own eyes, but Jehovah weighs the spirits.

Every way of a man is right in his own eyes, but Jehovah ponders the hearts.

I Jehovah search the heart, I examine the soul, even to give to each man according to his ways, according to the fruit of his doings.

For the Word of God is living and active, and sharper than any two-edged sword, piercing even to the division of soul and spirit, and of 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 who searches the inner thoughts and hearts. And I will give to each one of you according to your works.

Those who are of a perverse heart are an abomination to Jehovah, but the perfect in their way are His delight.

The sacrifice of the wicked is an abomination to Jehovah, but the prayer of the upright is His delight.

The way of the wicked is an abomination to Jehovah, but He loves him who pursues righteousness.

Jesus saw Nathanael coming toward Him, and said of him, Behold, an Israelite indeed, in whom is no deceit.

This being so, I myself always strive to have a conscience that is blameless toward God and men.

For our rejoicing is this: the testimony of our conscience, that we conducted ourselves in the world in simplicity and godly sincerity, not in fleshly wisdom but in the grace of God, and more abundantly toward you.

You are witnesses, and God also, how holily and uprightly and blamelessly we were among you who believe;

And the people rejoiced, for they had offered willingly, because with a perfect heart they had offered willingly unto Jehovah; and King David also rejoiced with great joy.

For we have great joy and encouragement in your love, because the hearts of the saints have been refreshed by you, brother.

Yes, brother, let me have joy from you in the Lord; refresh my heart in the Lord.
