1 Samuel 20:3-5

New Century Version

³ But David took an oath, saying, “Your father knows very well that you like me. He says to himself, ‘Jonathan must not know about it, or he will tell David.’ As surely as the Lord lives and as you live, I am only a step away from death!”

⁴ Jonathan said to David, “I’ll do anything you want me to do.”

⁵ So David said, “Look, tomorrow is the New Moon festival. I am supposed to eat with the king, but let me hide in the field until the third evening.
