Bede, on Prov 16:27

“The wicked man diggeth evil, and in his lips is a burning fire.”

“The wicked man digs up evil, etc. And the prophet says, They have labored to commit iniquity (Jeremiah IX). It can also specifically be understood about the heretic, who breaks up the most beautiful and flourishing fields of divine utterances with the harmful ploughshare of his tongue, to draw out from their inner parts wicked senses that are not there. In whose lips a fire burns, by which he destroys himself and his listeners forever. Hence James also says, The tongue is set among our members, defiling the whole body; and sets on fire the wheel of our birth, being set on fire by hell.”
