2 Corinthians 6:14-15 New American Standard Bible (NASB)
14 Do not be [a]bound together with unbelievers; for what partnership have righteousness and lawlessness, or what fellowship has light with darkness? 15 Or what harmony has Christ with [b]Belial, or [c]what has a believer in common with an unbeliever?
2 Corinthians 6:14-15 New International Version (NIV)
Warning Against Idolatry
14 Do not be yoked together with unbelievers. For what do righteousness and wickedness have in common? Or what fellowship can light have with darkness? 15 What harmony is there between Christ and Belial[a]? Or what does a believer have in common with an unbeliever?
