Sirach 7:6

6 Seek not to be judge, being not able to take away iniquity; lest at any time thou fear the person of the mighty, an stumblingblock in the way of thy uprightness.

4 Seek not of the Lord preeminence, neither of the king the seat of honour.
5 justify not thyself before the Lord; and boast not of thy wisdom before the king.
6 Seek not to be judge, being not able to take away iniquity; lest at any time thou fear the person of the mighty, an stumblingblock in the way of thy uprightness.
7 Offend not against the multitude of a city, and then thou shalt not cast thyself down among the people.
8 Bind not one sin upon another; for in one thou shalt not be unpunished.
