'Lightly' in the Bible

Wherefore Jehovah the God of Israel saith, I said indeed, Thy house and the house of thy father should walk before me for ever. But now Jehovah saith, Be it far from me; for them that honour me I will honour, and they that despise me shall be lightly esteemed.

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