1 Samuel 19:3

I will commune. Adversity proves the sincerity of true friendship. Jonathan well knew that David had no thought of usurping the throne, but was unable to convince Saul of that fact. Jonathan’s position was not easy, for he would be in the role of opposing the desires of a tyrant, and would be thought disloyal to his own father. However, as a true friend, Jonathan told David the truth about Saul, not to frighten, but to forewarn and assure him of a true friend’s allegiance. This was a real test for Jonathan. Jonathan had to decide between loyalty to his father and loyalty to David. It was impossible longer to be loyal to both. He demonstrated good judgment by conducting himself in such a way as to retain influence over his father and yet at the same time save David from certain death.
