'Merry' in the Bible

And I will say to my soul, Soul, thou hast much goods laid up for many years; take thine ease, eat, drink, and be merry.

And bring hither the fatted calf, and kill it; and let us eat, and be merry:

For this my son was dead, and is alive again; he was lost, and is found. And they began to be merry.

And he answering said to his father, Lo, these many years do I serve thee, neither transgressed I at any time thy commandment: and yet thou never gavest me a kid, that I might make merry with my friends:

It was meet that we should make merry, and be glad: for this thy brother was dead, and is alive again; and was lost, and is found.
