1 Samuel 20:6

20:6 If your father happens to miss me, you should say, ‘David urgently requested me to let him go to his city Bethlehem, for there is an annual sacrifice there for his entire family.’

1 Samuel 20:29

20:29 He said, ‘Permit me to go, for we are having a family sacrifice in the city, and my brother urged me to be there. So now, if I have found favor with you, let me go to see my brothers.’ For that reason he has not come to the king’s table.”
