(2.) Out of this abundance of wickedness in the heart their mouth speaks, and yet it does not always speak out the wickedness that is within, but, for the more effectually compassing the mischievous design, it is dissembled and covered with much fair speech (v. 3): Your lips have spoken lies; and again (v. 4), They speak lies, pretending kindness where they intend the greatest mischief; or by slanders and false accusations they blasted the credit and reputation of those they had a spite to and so did them a real mischief unseen, and perhaps by suborning witnesses against them took from them their estates and lives; for a false tongue is sharp arrows, and coals of juniper, and every thing that is mischievous. Your tongue has muttered perverseness. When they could not, for shame, speak their malice against their neighbours aloud, or durst not, for fear of being disproved and put to confusion, they muttered it secretly. Backbiters are called whisperers.
