And, of course, the Bible speaks directly against this kind of dishonest and deceptive speech:
π "Deceit is in the heart of those who plot evil, but joy comes to the promoters of peace." (Proverbs 12:20)
π "The wisdom of the prudent is to think about his way, but the folly of fools is deceit." (Proverbs 14:8)
π "A malicious man disguises himself with his lips, but he harbors evil in his heart. When his speech is charming, don't believe him; for there are seven abominations in his heart. His malice may be concealed by deception, but his wickedness will be exposed in the assembly." (Proverbs 26:24-26)
π "His mouth was smooth as butter, but his heart was war. His words were softer than oil, yet they were drawn swords." (Psalm 55:21)
π "Their tongue is a deadly arrow. It speaks deceit. One speaks peaceably to his neighbor with his mouth, but in his heart, he waits to ambush him." (Jeremiah 9:8)
π "Your tongue plots destruction, like a sharp razor, working deceitfully." (Psalm 52:2)
π "Like a madman who shoots firebrands, arrows, and death, is the man who deceives his neighbor and says, 'Am I not joking?'" (Proverbs 26:18-19)
π "But we have renounced the hidden things of shame, not walking in craftiness, nor handling the word of God deceitfully; but by the manifestation of the truth commending ourselves to every man's conscience in the sight of God." (2 Corinthians 4:2)
π "That we may no longer be children, tossed back and forth and carried about with every wind of doctrine, by the trickery of men, in craftiness, after the wiles of error." (Ephesians 4:14)
π "Regard the patience of our Lord as salvation; even as our beloved brother Paul also, according to the wisdom given to him, wrote to you; as also in all of his letters, speaking in them of these things. In those, there are some things that are hard to understand, which the ignorant and unsettled twist, as they also do the other Scriptures, to their own destruction."
(2 Peter 3:15-16)
