Behold, from all [that which we have learned], we can understand the great punishment that is fitting to befall [the speaker of slander, both] in this world and in The World to Come, [as a result of] this bitter sin. Therefore, Dovid HaMelech, Alav HaShalom, warned us, that when we desire to live the eternal life in The World to Come and [enjoy] good days in this world, [we] should, [first of all], guard [our] tongues from [speaking that which is] evil. How greatly must we be embarrassed and ashamed from [before] The Holy One, Blessed is He, on the High Holy Days [when] we entreat Him “Silence the Prosecutor and take the defense in his place”, [while] we ourselves, through our Lashon HaRa, arouse [the Prosecutor], giving him the power to prosecute [against us]. May HaShem place love, brotherhood, peace and friendship in our midst. [Amen!]
 This teaching is found in Eliyahu Rabbah, chapter 18, section 82.
