'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, be merry.

and bring the fatted calf, and kill it, and let us eat, and make merry:

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

But he answered and said to his father, Lo, these many years do I serve thee, and I never transgressed a commandment of thine; and yet thou never gavest me a kid, that I might make merry with my friends:

But it was meet to make merry and be glad: for this thy brother was dead, and is alive again ; and was lost, and is found.
