John 4:10-11
Jesus answered her, "If you [only] knew the [real] gift of God, and who it is that said to you, '[Please], give me a drink,' you would have asked Him, and He would have given you living water."
James 3:6
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].
Revelation 19:15
And a sharp sword came out of His mouth, with which He would strike down the nations. And He will rule them with an iron staff and will trample on [the grapes of] God Almighty's winepress of anger.
