'Joy' in the Bible

For to the person who [is] good in his eyes, he gives wisdom, knowledge, and joy; but to the sinner he gives the task of gathering and heaping up only to give [it] to [him who is] pleasing to him. This also [is] vanity and chasing wind!

Go--eat your food with joy, and drink your wine with a merry heart! For God already has approved your deeds.
