'Cheerful' in the Bible

Jezebel his wife said to him, "Now, you {rule} over Israel. Get up, eat food, and let your heart be {cheerful}. I myself will give you the vineyard of Naboth the Jezreelite."

Look [away] from me that I may be cheerful, before I depart and I am no more.

Shout joyfully to Yahweh, all the earth. Be cheerful and sing for joy and sing praises.

A cheerful heart is good medicine, but a downcast spirit will dry out bones.

Each one [should give] as he has decided in his heart, not {reluctantly} or from compulsion, for God loves a cheerful giver.

Is anyone among you suffering misfortune? He should pray. Is anyone cheerful? He should sing praise.
