'Festival' in the Bible

But the next day, on the second day of the New Moon, David's place was empty, and so Saul told his son Jonathan, "Why didn't Jesse's son come to the festival, either yesterday or today?"

Abigail returned to Nabal, and he was there in his house holding a festival like the festival of a king. Nabal's heart was glad, and he was very drunk, so she didn't tell him anything at all until morning.
