Proverbs 12:17-23

He who speaks truth [when he testifies] tells what is right, But a false witness utters deceit [in court]. There is one who speaks rashly like the thrusts of a sword, But the tongue of the wise brings healing. Truthful lips will be established forever, But a lying tongue is [credited] only for a moment. Deceit is in the heart of those who devise evil, But counselors of peace have joy. No harm befalls the righteous, But the wicked are filled with trouble. [Job 5:19; Ps 91:3; Prov 12:13; Is 46:4; Jer 1:8; Dan 6:27; 2 Tim 4:18] Lying lips are extremely disgusting to the LORD, But those who deal faithfully are His delight. [Prov 6:17; 11:20; Rev 22:15] A shrewd man is reluctant to display his knowledge [until the proper time], But the heart of [over-confident] fools proclaims foolishness. [Is 32:6]
