1 Samuel 20:4-9

4Then Jonathan said to David, "Whatever you say, I will do for you."

5David said to Jonathan, "Behold, tomorrow is the new moon, and I should not fail to sit at table with the king. But let me go, that I may hide myself in the field till the third day at evening.

6If your father misses me at all, then say, 'David earnestly asked leave of me to run to Bethlehem his city, for there is a yearly sacrifice there for all the clan.'

7If he says, 'Good!' it will be well with your servant, but if he is angry, then know that harm is determined by him.

8Therefore deal kindly with your servant, for you have brought your servant into a covenant of the Lord with you. But if there is guilt in me, kill me yourself, for why should you bring me to your father?"

9And Jonathan said, "Far be it from you! If I knew that it was determined by my father that harm should come to you, would I not tell you?"
