1 Samuel 18:18, 23

And David said to Saul, “Who am I, and who are my relatives, my father’s clan in Israel, that I should be son-in-law to the king?”

And Saul’s servants spoke those words in the ears of David. And David said, “Does it seem to you a little thing to become the king’s son-in-law, since I am a poor man and have no reputation?”
