1 Samuel 20:24-29

24And David hid himself in the field; and it was the new moon, and the king sat at table to eat.

25And the king sat on his seat, as at other times, on the seat by the wall; and Jonathan arose, and Abner sat by Saul's side, and David's place was empty.

26And Saul said nothing that day; for he thought, Something has befallen [him], that he is not clean: surely he is not clean.

27And it came to pass the next day after the new moon, the second [day of the month], as David's place was empty, that Saul said to Jonathan his son, Why has not the son of Jesse come to table, neither yesterday nor to-day?

28And Jonathan answered Saul, David earnestly asked leave of me [to go] to Bethlehem,

29and said, Let me go, I pray thee; for we have a family sacrifice in the city; and my brother himself has commanded me [to be there]; and now, if I have found favour in thy sight, let me go away, I pray thee, and see my brethren. He has therefore not come to the king's table.
