'Joyful' in the Bible

On the eighth day he sent the people away and they blessed the king. Then they went to their tents joyful and glad of heart for all the goodness that the Lord had shown to David His servant and to Israel His people.

Jezebel his wife said to him, “Do you now reign over Israel? Arise, eat bread, and let your heart be joyful; I will give you the vineyard of Naboth the Jezreelite.”
