Ben Sira 4:28

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

Ben Sira 4:28 In-Context

26 Accept no person against thy own person, nor against thy soul a lie.

27 Reverence not thy neighbour in his fall:

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

29 For 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.

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