Matthew 12:34
O degenerate race, how can ye, wicked as ye are, utter any thing that is good? for "'tis the overflowing of the heart that the mouth dischargeth."
Romans 3:13-14
their throat is an open sepulchre; with their tongues they have used deceit; the poison of asps is under their lips:
James 3:6-8
the tongue is a brand that sets the world in a combustion: it is but one of the numerous organs of the body, yet it can blast whole assemblies: tipp'd with infernal sulphur it sets the whole train of life in a blaze.
