Thematic Bible: First appearance of, a time of festivity

Tomorrow is the New Moon Festival, David replied, and I am supposed to eat with the king. But if it is all right with you, I will go and hide in the fields until the evening of the day after tomorrow. If your father notices that I am not at the table, tell him that I begged your permission to hurry home to Bethlehem. It is after all the time for the annual sacrifice there for my whole family.
