Proverbs 23:6-8 NIV

[6] Do not eat the food of a begrudging host, do not crave his delicacies; [7] for he is the kind of person who is always thinking about the cost. “Eat and drink,” he says to you, but his heart is not with you. [8] You will vomit up the little you have eaten and will have wasted your compliments.
