Proverbs 30:10-12 Wycliffe Bible (WYC)
10 Accuse thou not a servant to his lord, lest peradventure he curse thee, and thou fall down.
11 (There is) A generation that curseth his father, and that blesseth not his mother. (There be people who curse their fathers, and do not bless their mothers.)
12 (There is) A generation that seemeth clean to itself, and nevertheless is not washed from his filths. (There be people who seem clean to themselves, yet nevertheless be not washed from their filths.)
