'Hearted' in the Bible

When then you give money to the poor, do not make a noise about it, as the false-hearted men do in the Synagogues and in the streets, so that they may have glory from men. Truly, I say to you, They have their reward.

And when you make your prayers, be not like the false-hearted men, who take pleasure in getting up and saying their prayers in the Synagogues and at the street turnings so that they may be seen by men. Truly I say to you, They have their reward.

And when you go without food, be not sad-faced as the false-hearted are. For they go about with changed looks, so that men may see that they are going without food. Truly I say to you, They have their reward.

And our desire is that you will keep control over those whose lives are not well ordered, giving comfort to the feeble-hearted, supporting those with little strength, and putting up with much from all.
