Pro 23:1 When thou sittest to eat with a ruler, consider diligently what is before thee:
Pro 23:2 And put a knife to thy throat, if thou be a man given to appetite.
Pro 23:3 Be not desirous of his dainties: for they are deceitful meat.
Pro 23:4 Labour not to be rich: cease from thine own wisdom.
Pro 23:5 Wilt thou set thine eyes upon that which is not? for riches certainly make themselves wings; they fly away as an eagle toward heaven.
Pro 23:6 Eat thou not the bread of him that hath an evil eye, neither desire thou his dainty meats:
Pro 23:7 For as he thinketh in his heart, so is he: Eat and drink, saith he to thee; but his heart is not with thee.
Pro 23:8 The morsel which thou hast eaten shalt thou vomit up, and lose thy sweet words.
This passage is against overindulging. One of the commentaries makes note of the story of Esther, when Haman thought he was in quite the honor to be invited to the Queen's table. It was a trap though, as he found himself dead by the next day.
