1 Samuel 20:3

20:3 Taking an oath, David again said, “Your father is very much aware of the fact that I have found favor with you, and he has thought, ‘Don’t let Jonathan know about this, or he will be upset.’ But as surely as the Lord lives and you live, there is about one step between me and death!”

1 Samuel 20:34

20:34 Jonathan got up from the table enraged. He did not eat any food on that second day of the new moon, for he was upset that his father had humiliated David.
