'Lightly esteemed' in the Bible

Therefore the LORD God of Israel says, I said indeed that your house, and the house of your father, should walk before me forever: but now the LORD says, Be it far from me; for them that honor me I will honor, and they that despise me shall be lightly esteemed.

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