A wife is bound to her husband as long as he lives. But if her husband dies, she is free to marry anyone she wishes, as long as he belongs to the Lord.
Textus Receptus (TR) - 1 Corinthians 7:39 >Γυνὴ δέδεται νόμῳ ἐφ᾿ ὅσον χρόνον ζῇ ὁ ἀνὴρ αὐτῆς· ἐὰν δὲ κοιμηθῇ ὁ ἀνὴρ αὐτῆς, ἐλευθέρα ἐστὶν ᾧ θέλει γαμηθῆναι, μόνον ἐν Κυρίῳ.
