Yaakov 3:6-8

Orthodox Jewish Bible

⁶ And the lashon is an Eish, the lashon is made an Olam HaAvel (World of Iniquity) among our evarim (members), defiling with a stain kol haGuf (whole body), and setting ablaze the course of life, and is itself set by eish in Gehinnom. [MISHLE 16:27]

⁷ For every species both of wild animals and birds, reptiles and marine creatures is tamed and has been tamed by humankind.

⁸ But the Lashon no one of Bnei Adam is able to tame, an uncontrollable ra’ah (evil), full of deadly zuhamah (contamination).
