ה כִּי-יֵשְׁבוּ אַחִים יַחְדָּו, וּמֵת אַחַד מֵהֶם וּבֵן אֵין-לוֹ--לֹא-תִהְיֶה אֵשֶׁת-הַמֵּת הַחוּצָה, לְאִישׁ זָר: יְבָמָהּ יָבֹא עָלֶיהָ, וּלְקָחָהּ לוֹ לְאִשָּׁה וְיִבְּמָהּ.

5 Ἐὰν δὲ κατοικῶσιν ἀδελφοὶ ἐπὶ τὸ αὐτὸ καὶ ἀποθάνῃ εἷς ἐξ αὐτῶν, σπέρμα δὲ μὴ ᾖ αὐτῷ, οὐκ ἔσται ἡ γυνὴ τοῦ τεθνηκότος ἔξω ἀνδρὶ μὴ ἐγγίζοντι· ὁ ἀδελφὸς τοῦ ἀνδρὸς αὐτῆς εἰσελεύσεται πρὸς αὐτὴν καὶ λήμψεται αὐτὴν ἑαυτῷ γυναῖκα καὶ συνοικήσει αὐτῇ.
