James 3:6-8
And the tongue is [like] a fire [i.e., like that spark]. [For] the tongue, as a part of the body, is [like] the world of evil. It corrupts the entire life [of a person] and inflames the course of nature itself [i.e., it affects a person throughout his whole earthly existence], and is ignited by hell itself [i.e., the evil produced by the fiery tongue has hell as its source and destiny].
2 Peter 2:7-8
and if He rescued the righteous man Lot, who had become very disturbed by unrestrained wickedness [of the people there in Sodom].
Revelation 6:10
And they called out with a loud voice, "How long, holy and true Master, [will it be] before you judge the people living on earth and take revenge on them for [shedding] our blood?"
