'Heart' in the Bible

And it hath come to pass, at that time, I search Jerusalem with lights, And I have laid a charge on the men Who are hardened on their preserved things, Who are saying in their heart: Jehovah doth no good, nor doth He evil.

This is the exulting city that is dwelling confidently, That is saying in her heart, 'I am, and beside me there is none,' How hath she been for a desolation, A crouching-place for beasts, Every one passing by her doth hiss, He doth shake his hand!

Cry aloud, O daughter of Zion, shout, O Israel, Rejoice and exult with the whole heart, O daughter of Jerusalem.
