And keep watch over your heart with all care; so you will have life.

Putting an end to reasonings, and every high thing which is lifted up against the knowledge of God, and causing every thought to come under the authority of Christ;

For the evil-doer is lifted up because of the purpose of his heart, and he whose mind is fixed on wealth is turned away from the Lord, saying evil against him.

You offspring of snakes, how are you, being evil, able to say good things? because out of the heart's store come the words of the mouth. The good man out of his good store gives good things; and the evil man out of his evil store gives evil things.

The good man, out of the good store of his heart, gives good things; and the evil man, out of his evil store, gives evil: for out of the full store of the heart come the words of the mouth.

Give ear in heaven your living-place, acting in mercy; and give to every man whose secret heart is open to you, the reward of all his ways; for you, and you only, have knowledge of the hearts of all the children of men:

And you, Solomon my son, get knowledge of the God of your father, and be his servant with a true heart and with a strong desire, for the Lord is the searcher of all hearts, and has knowledge of all the designs of men's thoughts; if you make search for him, he will be near you; but if you are turned away from him, he will give you up for ever.

O let the evil of the evil-doer come to an end, but give strength to the upright: for men's minds and hearts are tested by the God of righteousness.

Let the words of my mouth and the thoughts of my heart be pleasing in your eyes, O Lord, my strength and my salvation.

Put me in the scales, O Lord, so that I may be tested; let the fire make clean my thoughts and my heart.

Will not God make search for it? for he sees the secrets of the heart.

You have knowledge when I am seated and when I get up, you see my thoughts from far away.

Evil designs are disgusting to the Lord, but the words of the clean-hearted are pleasing.

Every way of a man seems right to himself, but the Lord is the tester of hearts.

But, O Lord of armies, judging in righteousness, testing the thoughts and the heart, let me see your punishment come on them: for I have put my cause before you.
