Ecclesiasticus 8:9
8. Despise not the discourse of the wise, but acquaint thyself with their proverbs: for of them thou shalt learn instruction, and how to serve great men with ease.9. Miss not the discourse of the elders: for they also learned of their fathers, and of them thou shalt learn understanding, and to give answer as need requireth.10. Kindle not the coals of a sinner, lest thou be burnt with the flame of his fire.
