'Lightly' in the Bible

But Jeshurun waxed fat, and kicked: Thou art waxed fat, thou art grown thick, thou art become sleek; Then he forsook God who made him, And lightly esteemed the Rock of his salvation.

Therefore Jehovah, the God of Israel, saith, I said indeed that 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 honor me I will honor, and they that despise me shall be lightly esteemed.

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

Better is he that is lightly esteemed, and hath a servant, Than he that honoreth himself, and lacketh bread.
