Proverbs 23:5

1When thou sittest to eat with a ruler, consider diligently what is before thee:

2And put a knife to thy throat, if thou be a man given to appetite.

3Be not desirous of his dainties: for they are deceitful meat.

4Labour not to be rich: cease from thine own wisdom.

5Wilt thou set thine eyes upon that which is not? for riches certainly make themselves wings; they fly away as an eagle toward heaven.

6Eat thou not the bread of him that hath an evil eye, neither desire thou his dainty meats:

7For as he thinketh in his heart, so is he: Eat and drink, saith he to thee; but his heart is not with thee.

8The morsel which thou hast eaten shalt thou vomit up, and lose thy sweet words.

9Speak not in the ears of a fool: for he will despise the wisdom of thy words.
