New Living Translation
12 Then Jonathan told David, "I promise by the Lord, the God of Israel, that by this time tomorrow, or the next day at the latest, I will talk to my father and let you know at once how he feels about you. If he speaks favorably about you, I will let you know.
Jonathan faithfully promises that he would let David know how he found his father affected towards him.

True friendship rests on a firm basis, and is able to silence ambition, self-love, and undue regard for others.
