Proverbs 23:6-8

Amplified Bible

⁶ 
Do not eat the bread of a selfish man,
Or desire his delicacies;
⁷ 
For as he thinks in his heart, so is he [in behavior—one who manipulates].
He says to you, “Eat and drink,”
Yet his heart is not with you [but it is begrudging the cost].
⁸ 
The morsel which you have eaten you will vomit up,
And you will waste your compliments.
