'Merry' in the Bible

So both of them sat down and ate and drank together; and the girl’s father said to the man, “Please be willing to spend the night, and let your heart be merry.”

When the man arose to go along with his concubine and servant, his father-in-law, the girl’s father, said to him, “Behold now, the day has drawn to a close; please spend the night. Lo, the day is coming to an end; spend the night here that your heart may be merry. Then tomorrow you may arise early for your journey so that you may go home.”

While they were celebrating, behold, the men of the city, certain worthless fellows, surrounded the house, pounding the door; and they spoke to the owner of the house, the old man, saying, “Bring out the man who came into your house that we may have relations with him.”
