'Heart' in the Bible

And I applied my heart to seek and to search out by wisdom concerning all that is done under heaven: it is a sore travail that God hath given to the sons of men to be exercised therewith.

I communed with mine own heart, saying, Lo, I have gotten me great wisdom above all that were before me in Jerusalem; yea, my heart hath had great experience of wisdom and knowledge.

And I applied my heart to know wisdom, and to know madness and folly: I perceived that this also was a striving after wind.

I said in my heart, Come now, I will prove thee with mirth; therefore enjoy pleasure: and, behold, this also was vanity.

I searched in my heart how to cheer my flesh with wine, my heart yet guiding me with wisdom, and how to lay hold on folly, till I might see what it was good for the sons of men that they should do under heaven all the days of their life.

And whatsoever mine eyes desired I kept not from them; I withheld not my heart from any joy; for my heart rejoiced because of all my labor; and this was my portion from all my labor.

Then said I in my heart, As it happeneth to the fool, so will it happen even to me; and why was I then more wise? Then said I in my heart, that this also is vanity.

Therefore I turned about to cause my heart to despair concerning all the labor wherein I had labored under the sun.

For what hath a man of all his labor, and of the striving of his heart, wherein he laboreth under the sun?

For all his days are but'sorrows, and his travail is grief; yea, even in the night his heart taketh no rest. This also is vanity.

He hath made everything beautiful in its time: also he hath set eternity in their heart, yet so that man cannot find out the work that God hath done from the beginning even to the end.

I said in my heart, God will judge the righteous and the wicked; for there is a time there for every purpose and for every work.

I said in my heart, It is because of the sons of men, that God may prove them, and that they may see that they themselves are but as beasts.

Be not rash with thy mouth, and let not thy heart be hasty to utter anything before God; for God is in heaven, and thou upon earth: therefore let thy words be few.

For he shall not much remember the days of his life; because God answereth him in the joy of his heart.

It is better to go to the house of mourning than to go to the house of feasting: for that is the end of all men; and the living will lay it to his heart.

Sorrow is better than laughter; for by the sadness of the countenance the heart is made glad.

The heart of the wise is in the house of mourning; but the heart of fools is in the house of mirth.

for oftentimes also thine own heart knoweth that thou thyself likewise hast cursed others.

I turned about, and my heart was set to know and to search out, and to seek wisdom and the reason of things , and to know that wickedness is folly, and that foolishness is madness.

And I find more bitter than death the woman whose heart is snares and nets, and whose hands are bands: whoso pleaseth God shall escape from her; but the sinner shall be taken by her.

Whoso keepeth the commandment shall know no evil thing; and a wise man's heart discerneth time and judgment:

All this have I seen, and applied my heart unto every work that is done under the sun: there is a time wherein one man hath power over another to his hurt.

Because sentence against an evil work is not executed speedily, therefore the heart of the sons of men is fully set in them to do evil.

When I applied my heart to know wisdom, and to see the business that is done upon the earth (for also there is that neither day nor night seeth sleep with his eyes),

For all this I laid to my heart, even to explore all this: that the righteous, and the wise, and their works, are in the hand of God; whether it be love or hatred, man knoweth it not; all is before them.

This is an evil in all that is done under the sun, that there is one event unto all: yea also, the heart of the sons of men is full of evil, and madness is in their heart while they live, and after that they go to the dead.

Go thy way, eat thy bread with joy, and drink thy wine with a merry heart; for God hath already accepted thy works.

A wise man's heart is at his right hand; but a fool's heart at his left.

Rejoice, O young man, in thy youth, and let thy heart cheer thee in the days of thy youth, and walk in the ways of thy heart, and in the sight of thine eyes; but know thou, that for all these things God will bring thee into judgment.

Therefore remove sorrow from thy heart, and put away evil from thy flesh; for youth and the dawn of life are vanity.
