1 Samuel 20:5-8

So David said, “Look, tomorrow is the New Moon feast, and I am supposed to dine with the king; but let me go and hide in the field until the evening of the day after tomorrow. If your father misses me at all, tell him, ‘David earnestly asked my permission to hurry to Bethlehem, his hometown, because an annual sacrifice is being made there for his whole clan.’ If he says, ‘Very well,’ then your servant is safe. But if he loses his temper, you can be sure that he is determined to harm me.As for you, show kindness to your servant, for you have brought him into a covenant with you before the Lord. If I am guilty, then kill me yourself! Why hand me over to your father?”
