וַיֹּ֣אמֶר הַגֹּאֵ֗ל לֹ֤א אוּכַל֙ לגאול־[לִגְאָל־] לִ֔י פֶּן־אַשְׁחִ֖ית אֶת־נַחֲלָתִ֑י גְּאַל־לְךָ֤ אַתָּה֙ אֶת־גְּאֻלָּתִ֔י כִּ֥י לֹא־אוּכַ֖ל לִגְאֹֽל׃
그 기업 무를 자가 가로되 나는 내 기업에 손해가 있을까하여 나를 위하여 무르지 못하노니 나의 무를 권리를 네가 취하라 나는 무르지 못하겠노라

לבלתי נתן זרע לאחיו, “not to provide semen for his brother;” we find similar considerations in the Book of Ruth 4,6 when a potential redeemer declined to perform a levirate marriage with Ruth;” [as the latter had not been a Jewess, and a Moabite even, his consideration was not sinful. Ed.] Besides, there was another redeemer willing and anxious to perform such a ritual for her.
