1 Samuel 18:18, 23

And David said unto Saul, Who am I? and what is my life, or my father's family in Israel, that I should be son in law to the king?

And Saul's servants spake those words in the ears of David. And David said, Seemeth it to you a light thing to be a king's son in law, seeing that I am a poor man, and lightly esteemed?
