Proverbs 23:5-9

Wilt thou set thine eyes upon that which is not? for riches certainly make themselves wings; they fly away as an eagle toward heaven.

Eat thou not the bread of him that hath an evil eye, neither desire thou his dainty meats:

For as he thinketh in his heart, so is he: Eat and drink, saith he to thee; but his heart is not with thee.

The morsel which thou hast eaten shalt thou vomit up, and lose thy sweet words.

Speak not in the ears of a fool: for he will despise the wisdom of thy words.
