Deuteronomy 21:13

וְהֵסִ֩ירָה֩ אֶת־שִׂמְלַ֨ת שִׁבְיָ֜הּ מֵעָלֶ֗יהָ וְיָֽשְׁבָה֙ בְּבֵיתֶ֔ךָ וּבָֽכְתָ֛ה אֶת־אָבִ֥יהָ וְאֶת־אִמָּ֖הּ יֶ֣רַח יָמִ֑ים וְאַ֨חַר כֵּ֜ן תָּב֤וֹא אֵלֶ֙יהָ֙ וּבְעַלְתָּ֔הּ וְהָיְתָ֥ה לְךָ֖ לְאִשָּֽׁה׃

καὶ καὶ περιελεῖς τὰ ἱμάτια τῆς αἰχμαλωσίας ἀπ’ αὐτῆς, καὶ καθιεῖται ἐν τῇ οἰκίᾳ σου καὶ κλαύσεται τὸν πατέρα καὶ τὴν μητέρα μηνὸς ἡμέρας· καὶ μετὰ ταῦτα εἰσελεύσῃ πρὸς αὐτὴν καὶ συνοικισθήσῃ αὐτῇ, καὶ ἔσται σου γυνή.

Y se quitará el vestido de su cautiverio, y quedaráse en tu casa: y llorará á su padre y á su madre el tiempo de un mes: y después entrarás á ella, y tu serás su marido, y ella tu mujer.

and put aside the clothing of her captivity. After she has lived in your house a full month and mourned her father and mother, you may have relations with her and be her husband, and she shall be your wife.
