But Jeshurun waxed fat, and kicked: thou hast waxed fat, thou art grown thick, thou art covered with fatness; then he forsook God who made him, and lightly esteemed the Rock of his salvation.

Wherefore the LORD God of Israel saith, I said indeed that thy house, and the house of thy father should walk before me for ever: but now the LORD 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 spoke 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?
