Proverbs 23:1-3

Wycliffe Bible

23 When thou sittest to eat with the prince, perceive thou diligently what things be set before thy face,

² and set thou a coulter in thy throat. If nevertheless thou hast power on thy soul, (and set thou a knife at thy own throat, if thou hast not power over thy self.)

³ desire thou not of his meats, in whom is the bread of lying. (Do not thou desire any of his food, for he is not what he seemeth to be/for this is not what it seemeth to be.)
