Proverbs 23:8
King James Version
“The morsel thou hast eaten shalt thou vomit up, and lose thy sweet words.”
Context
5Wilt thou set thine eyes upon that which is not? for certainly make themselves wings; they fly away as an eagle toward heaven.
6Eat thou not the bread of an evil eye, neither desire thou his dainty meats:
7For as he thinketh in his heart, so he: Eat and drink, saith he to thee; but his heart not with thee.
8The morsel thou hast eaten shalt thou vomit up, and lose thy sweet words.
9Speak not in the ears of a fool: for he will despise the wisdom of thy words.
10Remove not the old landmark; and enter not into the fields of the fatherless:
11For their redeemer mighty; he shall plead their cause with thee.
