'Merry' in the Bible

So David said to Michal, “It was before the Lord [that I did this], who chose me above your father and all his house, to appoint me as ruler over Israel, the people of the Lord. Therefore I will celebrate [in pure enjoyment] before the Lord.

Now Absalom had commanded his servants, saying, Mark ye now when Amnon's heart is merry with wine, and when I say unto you, Smite Amnon; then kill him, fear not: have not I commanded you? be courageous, and be valiant.
