Proverbs 19:26-28

Revised Standard Version Catholic Edition

²⁶ He who does violence to his father and chases away his mother
    is a son who causes shame and brings reproach.
²⁷ Cease, my son, to hear instruction
    only to stray from the words of knowledge.
²⁸ A worthless witness mocks at justice,
    and the mouth of the wicked devours iniquity.
