“A worthless person, a wicked man, walks with a perverse mouth [fraudulent deceitful speech]; he winks with his eyes, he shuffles his feet, he points with his fingers; perversity is in his heart, he devises evil continually, he sows discord. Therefore his calamity shall come suddenly; suddenly he shall be broken without remedy.” Proverbs 6:12-15.
“These six things the Lord hates, yes, seven are an abomination to Him: a proud look, a lying tongue, hands that shed innocent blood, a heart that devises wicked plans, feet that are swift in running to evil, a false witness who speaks lies, and one who sows discord among brethren.” Proverbs 6:16-19.
“…who [Jesus, God the Son], being in the form of God, did not consider it robbery to be equal with God, but made Himself of no reputation, taking the form of a bondservant, and coming in the likeness of men. And being found in appearance as a man, He humbled Himself and became obedient to the point of death, even the death of the cross. Therefore God also has highly exalted Him and given Him the name which is above every name, that at the name of Jesus every knee should bow, of those in heaven, and of those on earth, and of those under the earth, and that every tongue should confess that Jesus Christ is Lord, to the glory of God the Father.” Philippians 2:6-11.
“Multitudes, multitudes in the valley of decision! For the day of the Lord is near in the valley of decision. The sun and moon will grow dark, and the stars will diminish their brightness.” Joel 3:14-15.
