Proverbs 23:8

When thou perceivest his churlish disposition and carriage, his meat will be loathsome to thee, and thou wilt wish either that thou hadst never eaten it, or that thou couldst vomit it up again. Thy sweet words; thy pleasant discourse, wherewith thou didst adorn his table, and design both to delight and profit him, is lost, and of no effect to him, and thou wilt be ready to repent of it.
