LXX Deut 20:7

καὶ τίς ὁ ἄνθρωπος ὅστις μεμνήστευται γυναῖκα καὶ οὐκ ἔλαβεν αὐτήν ; πορευέσθω καὶ ἀποστραφήτω εἰς τὴν οἰκίον αὐτοῦ, μὴ ἀποθάνῃ ἐν τῷ πολέμῳ καὶ ἄνθρωπος ἕτερος λήμψεται αὐτήν.

Has any man become pledged to a woman and not married her? Let him return home, or he may die in battle and another man marry her.”
