The Gemara taught that the Torah three times prohibits verbally mistreating a convert — in , "And you shall neither mistreat a convert"; in , "And when a convert lives in your land, you shall not mistreat him"; and in , "And you shall not mistreat, each man his colleague." And the Torah similarly three times prohibits oppressing the convert — in , "And you shall neither mistreat a convert, nor oppress him"; in , "And you shall not oppress a convert"; and in , "And you shall not be to him like a creditor." Reading , "And you shall not mistreat a convert nor oppress him, because you were strangers in the land of Egypt," a Baraita reported that Rabbi Nathan taught that one should not mention in another a defect that one has oneself. Thus, since the Jewish people were themselves strangers, they should not demean a convert because he is a stranger in their midst. And this explains the adage that one who has a person hanged in the family does not say to another member of the household: Hang a fish for me, as the mention of hanging is demeaning for that family.
