Sirach 51:5

5 From the depth of the belly of hell, from an unclean tongue, and from lying words.

Sirach 51:5 In-Context

3 And hast delivered me, according to the multitude of they mercies and greatness of thy name, from the teeth of them that were ready to devour me, and out of the hands of such as sought after my life, and from the manifold afflictions which I had;
4 From the choking of fire on every side, and from the midst of the fire which I kindled not;
5 From the depth of the belly of hell, from an unclean tongue, and from lying words.
6 By an accusation to the king from an unrighteous tongue my soul drew near even unto death, my life was near to the hell beneath.
7 They compassed me on every side, and there was no man to help me: I looked for the succour of men, but there was none.
