'Heart' in the Bible

And it shall come to pass at that time, that I will search Jerusalem with candles, and punish the men that are settled on their lees: that say in their heart, The LORD will not do good, neither will he do evil.

Make search for the Lord, all you quiet ones of the earth, who have done what is right in his eyes; make search for righteousness and a quiet heart: it may be that you will be safely covered in the day of the Lord's wrath.

This is the rejoicing city that dwelt carelessly, that said in her heart, I am, and there is none beside me: how is she become a desolation, a place for beasts to lie down in! every one that passeth by her shall hiss, and wag his hand.

I have said, "If only you would fear me, if only you would take my instructions to heart.' Then their houses would not have been torn down. I have chastened them, but they were eager to corrupt everything they were doing."

Sing, O daughter of Zion; shout, O Israel; be glad and rejoice with all the heart, O daughter of Jerusalem.
