'Heart' in the Bible

And kept the feast of unleavened bread for seven days with joy: for the Lord had made them full of joy, by turning the heart of the king of Assyria to them to give them help in the work of the house of God, the God of Israel.

Praise be to the Lord, the God of our fathers, who has put such a thing into the heart of the king, to make fair the house of the Lord which is in Jerusalem;

Up, now! for this is your business, and we are with you; take heart and do it.
