Ben Sira 23:8

8 The sinner shall be left in his foolishness: both the evil speaker and the proud shall fall thereby.

Ben Sira 23:8 In-Context

6 Let not the greediness of the belly nor lust of the flesh take hold of me; and give not over me thy servant into an impudent mind.
7 Hear, O ye children, the discipline of the mouth: he that keepeth it shall never be taken in his lips.
8 The sinner shall be left in his foolishness: both the evil speaker and the proud shall fall thereby.
9 Accustom not thy mouth to swearing; neither use thyself to the naming of the Holy One.
10 For as a servant that is continually beaten shall not be without a blue mark: so he that sweareth and nameth God continually shall not be faultless.
