1 Samuel 20:4-9

4Then Jonathan said to David, “Whatever you desire, I will do for you.”

5So David told him, “Look, tomorrow is the New Moon,1 and I am supposed to dine with the king. Instead, let me go and hide in the field until the third evening from now. 6If your father misses me at all, tell him, ‘David urgently requested my permission to hurry to Bethlehem, his hometown, because there is an annual sacrifice for his whole clan.’ 7If he says, ‘Good,’ then your servant is safe, but if he is enraged, you will know he has evil intentions. 8Therefore show kindness to your servant, for you have brought me into a covenant with you before the LORD. If there is iniquity in me, then kill me yourself; why should you bring me to your father?”

9“Never!” Jonathan replied. “If I ever found out that my father had evil intentions against you, would I not tell you?”
