Proverbs 23:8
The morsel which thou hast eaten shalt thou vomit up, and lose thy sweet words.
The morsel which thou hast eaten, shalt thou vomit up,.... It shall turn in thy stomach, thou shall not be able to keep it, when thou understandest thou art not welcome; or thou wilt wish thou hadst never eaten a bit, or that thou couldest vomit up what thou hast; so disagreeable is the thought of being unwelcome, or when this appears to be the case;
and lose thy sweet words; expressed in thankfulness to the master of the feast, in praise of his food, in pleasantry with him, and the other guests at table; all which are repented of when a man finds he is not welcome.
