Ben Sira 23:7

7 Hear, O ye children, the discipline of the mouth: and he that will keep it shall not perish by his lips, nor be brought to fall into most wicked works.

Ben Sira 23:7 In-Context

5 Give me not haughtiness of my eyes, and turn away from me all coveting.

6 Take from me the greediness of the belly, and let not the lusts of the flesh take hold of me, and give me not over to a shameless and foolish mind.

7 Hear, O ye children, the discipline of the mouth: and he that will keep it shall not perish by his lips, nor be brought to fall into most wicked works.

8 A sinner is caught in his own vanity, and the proud and the evil speakers shall fall thereby.

9 Let not thy mouth be accustomed to swearing: for in it there are many falls.
