Proverbs 23:4-8 - Labour not to be rich: cease from thine own wisdom.

Labour not to be rich: cease from thine own wisdom. 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.
