8The morsel, which thou hast eaten, thou shalt vomit up; And thou wilt have thrown away thy sweet words.
9Speak not in the ears of a fool; For he will despise the wisdom of thy words.
10Remove not the ancient landmark, And enter not into the fields of the fatherless!
11For their avenger is mighty; He will maintain their cause against thee.
