Proverbs 6:14

14 Frowardness [is] in his heart, devising evil at all times, Contentions he sendeth forth.

Proverbs 6:14 In-Context

12 A man of worthlessness, a man of iniquity, Walking [with] perverseness of mouth,
13 Winking with his eyes, speaking with his feet, Directing with his fingers,
14 Frowardness [is] in his heart, devising evil at all times, Contentions he sendeth forth.
15 Therefore suddenly cometh his calamity, Instantly he is broken -- and no healing.
16 These six hath Jehovah hated, Yea, seven [are] abominations to His soul.
