'New Moon' in the Bible

David told Jonathan, "Look, the New Moon is tomorrow, and I'm expected to sit down with the king to eat. Let me go so I can hide in the field until the evening of the day after tomorrow.

Jonathan told him, "Tomorrow is the New Moon, and you will be missed because your seat is empty.

David hid in the field. When the New Moon arrived, the king sat down to eat.

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?"

So on the second day of the New Moon Jonathan angrily got up from the table without eating because he was upset about David, and because his father had humiliated him.
