Sirach 27:12

Ben Sira, Ecclesiasticus

10 A lion lies in wait for prey; so does sin for evildoers. 11 The conversation of the godly is always wise, but the fool changes like the moon. 12 Among stupid people limit your time, but among thoughtful people linger on. 13 The talk of fools is offensive, and their laughter is wantonly sinful. 14 Their cursing and swearing make one's hair stand on end, and their quarrels make others stop their ears.

Clement of Alexandria Stromata Book 5.3

"And pray that we may be delivered from unreasonable and wicked men: for all men have not faith." And the Poetics of Cleanthes, the Stoic, writes to the following effect: "Look not to glory, wishing to be suddenly wise, And fear not the undiscerning and rash opinon of the many; For the multitude has not an intelligent, or wise, or right judgment, And it is in few men that you will find this." And more sententiously the comic poet briefly says: "It is a shame to judge of what is right by much noise." For they heard, I think, that excellent wisdom, which says to us, "Watch your opportunity in the midst of the foolish, and in the midst of the intelligent continue." And again, "The wise will conceal sense." For the many demand demonstration as a pledge of truth, not satisfied with the bare salvation by faith.
