1 Samuel 20:4-8

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

So David said to Jonathan, “Behold, tomorrow is the new moon, and I am obligated to sit down to eat with the king. But let me go so that I may hide myself in the field until the third evening.

If your father misses me at all, then say, ‘David earnestly requested leave of me to run to Bethlehem, his city, because it is the yearly sacrifice there for the whole family.’

If he says, ‘That is good,’ your servant will be safe; but if he is very angry, be aware that he has decided on evil.

So deal kindly with your servant, for you have brought your servant into a covenant of the Lord with you. But if I am guilty of wrongdoing, kill me yourself; for why then should you bring me to your father?”
