Proverbs 23:7 in the King James Version
For as he thinketh in his heart, so is he: Eat and drink, saith he to thee; but his heart is not with thee.
Context
6 Don’t eat the food of him who has a stingy eye, and don’t crave his delicacies,
7 for as he thinks about the cost, so he is. “Eat and drink!” he says to you, but his heart is not with you.
8 You will vomit up the morsel which you have eaten and waste your pleasant words.
