'Heart' in the Bible

Shall not they teach thee, and tell thee, And utter words out of their heart?

He is wise in heart, and mighty in strength: Who hath hardened himself against him, and prospered?-

Yet these things thou didst hide in thy heart; I know that this is with thee:

If thou set thy heart aright, And stretch out thy hands toward him;

Why doth thy heart carry thee away? And why do thine eyes flash,

They conceive mischief, and bring forth iniquity, And their heart prepareth deceit.

For thou hast hid their heart from understanding: Therefore shalt thou not exalt them .

My days are past, my purposes are broken off, Even the thoughts of my heart.

Whom I, even I, shall see, on my side, And mine eyes shall behold, and not as a stranger. My heart is consumed within me.

Receive, I pray thee, the law from his mouth, And lay up his words in thy heart.

For God hath made my heart faint, And the Almighty hath terrified me;

My righteousness I hold fast, and will not let it go: My heart shall not reproach me'so long as I live.

The blessing of him that was ready to perish came upon me; And I caused the widow's heart to sing for joy.

My heart is troubled, and resteth not; Days of affliction are come upon me.

If my step hath turned out of the way, And my heart walked after mine eyes, And if any spot hath cleaved to my hands:

If my heart hath been enticed unto a woman, And I have laid wait at my neighbor's door;

And my heart hath been secretly enticed, And my mouth hath kissed my hand:

My words'shall utter the uprightness of my heart; And that which my lips know they shall speak sincerely.

If he set his heart upon himself, If he gather unto himself his spirit and his breath;

But they that are godless in heart lay up anger: They cry not for help when he bindeth them.

Yea, at this my heart trembleth, And is moved out of its place.

Men do therefore fear him: He regardeth not any that are wise of heart.

His heart is as firm as a stone; Yea, firm as the nether millstone.
