Sirach 4:30DRA

28And refrain not to speak in the time of salvation. Hide not thy wisdom in her beauty.

29For by the tongue wisdom is discerned: and understanding, and knowledge, and learning by the word of the wise, and steadfastness in the works of justice.

30In nowise speak against the truth, but be ashamed of the lie of thy ignorance.

31Be not ashamed to confess thy sins, but submit not thyself to every man for sin.

32Resist not against the face of the mighty, and do not strive against the stream of the river.
