Sirach 22:26

Ben Sira, Ecclesiasticus

23 Gain the trust of your neighbor in his poverty, so that you may rejoice with him in his prosperity. Stand by him in time of distress, so that you may share with him in his inheritance. 24 The vapor and smoke of the furnace precede the fire; so insults precede bloodshed. 25 I am not ashamed to shelter a friend, and I will not hide from him. 26 But if harm should come to me because of him, whoever hears of it will beware of him. 27 Who will set a guard over my mouth, and an effective seal upon my lips, so that I may not fall because of them, and my tongue may not destroy me?

Ambrose On the Duty of the Clergy 2.8

42 But if we have found a man that by the vigour of his character, by his strength of mind and influence, stands forth above all others, and further, is better fitted by example and experience than others; that can put an end to immediate dangers, foresee future ones, point out those close at hand, can explain a subject, bring relief in time, is ready not only to give advice but also to give help — in such a man confidence is placed, so that he who seeks advice can say: Though evil should happen to me through him, I will bear it.
