Sirach 22:30-33 Catholic Public Domain Version (CPDV)

30. Just as the steam from an oven, or the smoke from a fire, rises up before a flame, so also do curses and insults and threats rise up before bloodshed.

31. I shall not be ashamed to greet a friend, nor shall I hide myself from his face. And if misfortunes befall me because of him, I will endure.

32. Anyone who hears of this will be wary around him.

33. Who will provide a keeper for my mouth, and a reliable seal over my lips, so that I may not fall because of them, and so that my tongue does not destroy me?
