'Hearts' in the Bible

And he said, O Lord, the God of Israel, there is no God like you in heaven or on earth; keeping faith and mercy unchanging for your servants, while they go in your ways with all their hearts;

Then give ear from heaven your living-place, answering with forgiveness, 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 the children of men;)

And on the twenty-third day of the seventh month, he sent the people away to their tents, full of joy and glad in their hearts, because of all the good which the Lord had done to David and to Solomon and to Israel his people.

And after them, from all the tribes of Israel, all those whose hearts were fixed and true to the Lord, the God of Israel, came to Jerusalem to make offerings to the Lord, the God of their fathers.

For the eyes of the Lord go this way and that, through all the earth, letting it be seen that he is the strong support of those whose hearts are true to him. In this you have done foolishly, for from now you will have wars.

The high places, however, were not taken away, and the hearts of the people were still not true to the God of their fathers.

Then Hezekiah made answer and said, Now that you have given yourselves to the Lord, come near and take offerings and praise-offerings into the house of the Lord. So all the people took in offerings and praise-offerings: and those whose hearts were moved, took in burned offerings.
