לֹ֣א תַטֶּ֔ה מִשְׁפַּ֖ט גֵּ֣ר יָת֑וֹם וְלֹ֣א תַחֲבֹ֔ל בֶּ֖גֶד אַלְמָנָֽה׃
Ne fausse pas le droit de l’étranger ni celui de l’orphelin, et ne saisis pas comme gage le vêtement de la veuve.
Sifrei Devarim
(Devarim 14:29) "and the stranger, and the orphan, and the widow that are in your gates": I might think (that they take poor-tithe) whether or not they are needy. And do not wonder about this, for it is written (Ibid. 24;17) "You shall not take as a pledge the garment of a widow" — whether rich or poor. It is, therefore, written (Vayikra 23:22) "To the poor man and to the stranger shall you leave them." Just as a poor man is needy, so, all (to take poor-tithe) must be needy.
Sifrei Devarim
(Devarim 24:17) "You shall not pervert the judgment of a stranger and an orphan": What is the intent of this? Is it not already written (Ibid. 16:19) "You shall not pervert judgment"? Its intent is to teach that one who perverts the judgment of a stranger transgresses two negative commandments.
