Ephesians 4:18 in the King James Version
Having the understanding darkened, being alienated from the life of God through the ignorance that is in them, because of the blindness of their heart:
Context
17 This I say therefore, and testify in the Lord, that you no longer walk as the rest of the Gentiles also walk, in the futility of their mind,
18 being darkened in their understanding, alienated from the life of God because of the ignorance that is in them, because of the hardening of their hearts.
19 They, having become callous, gave themselves up to lust, to work all uncleanness with greediness.
