Proverbs 23:1-5 NIV

When you sit to dine with a ruler, note well what is before you, and put a knife to your throat if you are given to gluttony. Do not crave his delicacies, for that food is deceptive. Do not wear yourself out to get rich; do not trust your own cleverness. Cast but a glance at riches, and they are gone, for they will surely sprout wings and fly off to the sky like an eagle.
