1 Samuel 20:5; 1 Samuel 20:25

5 So David said to Jonathan, "Behold, tomorrow is the new moon, and I ought to sit down to eat with the king. But let me go, that I may hide myself in the field until the third evening.

25 The king sat on his seat as usual, the seat by the wall; then Jonathan rose up and Abner sat down by Saul's side, but David's place was empty.
