Ben Sira 4:23

23 And refrain not to speak, when there is occasion to do good, and hide not thy wisdom in her beauty.

Ben Sira 4:23 In-Context

21 For there is a shame that bringeth sin; and there is a shame which is glory and grace.
22 Accept no person against thy soul, and let not the reverence of any man cause thee to fall.
23 And refrain not to speak, when there is occasion to do good, and hide not thy wisdom in her beauty.
24 For by speech wisdom shall be known: and learning by the word of the tongue.
25 In no wise speak against the truth; but be abashed of the error of thine ignorance.
