A man must free the widow of his childless brother from the obligation to marry him if he is unwilling to marry her

then his brother's wife shall come to him in the sight of the elders, and pull his sandal off his foot and spit in his face; and she shall declare, 'Thus it is done to the man who does not build up his brother's house.'

Hebrew

ט וְנִגְּשָׁה יְבִמְתּוֹ אֵלָיו, לְעֵינֵי הַזְּקֵנִים, וְחָלְצָה נַעֲלוֹ מֵעַל רַגְלוֹ, וְיָרְקָה בְּפָנָיו; וְעָנְתָה, וְאָמְרָה, כָּכָה יֵעָשֶׂה לָאִישׁ, אֲשֶׁר לֹא-יִבְנֶה אֶת-בֵּית אָחִיו.

Greek

9 καὶ προσελθοῦσα ἡ γυνὴ τοῦ ἀδελφοῦ αὐτοῦ ἔναντι τῆς γερουσίας καὶ ὑπολύσει τὸ ὑπόδημα αὐτοῦ τὸ ἓν ἀπὸ τοῦ ποδὸς αὐτοῦ καὶ ἐμπτύσεται εἰς τὸ πρόσωπον αὐτοῦ καὶ ἀποκριθεῖσα ἐρεῖ Οὕτως ποιήσουσιν τῷ ἀνθρώπῳ, ὃς οὐκ οἰκοδομήσει τὸν οἶκον τοῦ ἀδελφοῦ αὐτοῦ·
