As charcoal to embers and as wood to fire, so is a quarrelsome person for kindling strife. (NIV)
As coals are to hot embers and as wood to fire, so is a quarrelsome man to inflame strife. [Prov. 15:18; 29:22.] (AMP)
As coals are to burning coals, and wood to fire; so is a contentious man to kindle strife. (KJV)
