Halakhah zu Wajikra 27:8

And since the matter of arranging [this debt] has come to our hand, we shall write here that which they, may their memory be blessed, said about a [general] debtor in the chapter [entitled] HaMekabel Sadeh Mechavero in Bava Metzia 113b: That there we say, "A teacher taught in front of Rav Nachman bar Yitzchak, 'In the [same] way that we arrange things with appraisals, so do we arrange things with a debtor.'" And they brought many challenges and solutions and the end of the matter is that which the Gemara brings, "A story of Eliyahu, who Rabbah bar Avoua found standing in a graveyard of gentiles. He said to him, 'What is [the law] about their arranging things for a debtor?'" And Rashi, may his memory be blessed, and others had a textual variant [instead], "From where [do we know] about their arranging things for a debtor?" [This is] meaning to say, it was obvious to Rabbah bar Avoua that we arrange [things for a debtor], but he was asking Eliyahu, from which verse we learn it. "And Eliyahu answered him, 'That this is how we learn it, "destitution, destitution," from appraisals.'" [This is] meaning to say that it is written about a loan (Leviticus 25:35), "And if your brother becomes destitute and his hand falters with you, you shall strengthen him" - which is a loan, as it is written at its end (Leviticus 25:35), "Do not take from him interest or increase, etc."; and it is written about appraisals (Leviticus 27:8), "And if he is destitute from [paying] the appraisal" - and the received tradition (Arakhin 24a) comes [that its understanding is], revive him from his appraisal.
