Ben Sira 22:27

27 Who shall set a watch before my mouth and a seal of wisdom upon my lips, that I fall not suddenly by them, and that my tongue destroy me not?

Ben Sira 22:27 In-Context

25 I will not be ashamed to defend a friend, neither will I hide myself from him.

26 And if any evil happen unto me by him, every one that heareth it will beware of him.

27 Who shall set a watch before my mouth and a seal of wisdom upon my lips, that I fall not suddenly by them, and that my tongue destroy me not?
