1 Samuel 20:4-9

4Then Jonathan said to David, “Whatever you say, I will do for you!”

5So David said to Jonathan, “Look, tomorrow is the New Moon, when I am supposed to sit down with the king to eat. Instead, let me go hide myself in the countryside until the third evening.

6If your father misses me at all, then say: ‘David earnestly asked my permission to run to Beth-lehem, his town, for it is the annual sacrifice there for the whole family.’

7If he says thus, ‘Very well,’ then your servant is safe; but if he becomes very angry, then know that he is determined to harm me.

8Therefore deal kindly with your servant, for you have brought your servant into a covenant of Adonai with you. But if there is any iniquity in me, then kill me yourself! Why should you bring me to your father?”

9Jonathan replied, “Far be it from you! For if I know for sure that my father has determined evil to come on you, then wouldn’t I tell you about it?”
