Mark 9:48-50

Young's Literal Translation

⁴⁸ where their worm is not dying, and the fire is not being quenched;

⁴⁹ for every one with fire shall be salted, and every sacrifice with salt shall be salted.

⁵⁰ The salt [is] good, but if the salt may become saltless, in what will ye season [it]? Have in yourselves salt, and have peace in one another.'
