4 Adulterers, do you not know that friendship with the world means hostility toward God? So whoever decides to be the world’s friend makes himself God’s enemy.
Darby
4 Adulteresses, know ye not that friendship with the world is enmity with God? Whoever therefore is minded to be [the] friend of the world is constituted enemy of God.
KJV
4 Ye adulterers and adulteresses, know ye not that the friendship of the world is enmity with God? whosoever therefore will be a friend of the world is the enemy of God.
