Deuteronomy 24:17 - Matthew Poole's English Annotations on the Holy Bible

Nor of the fatherless; nor of the widow, which is to be supplied out of the last member; nor indeed of any other person; but he particularly mentions these, partly because men are most apt to wrong such helpless persons, and partly because God is pleased especially to charge himself, and so to charge others, with the care of those who have no other refuge. See Isaiah 1:23 Jeremiah 5:28. A widow's raiment, to wit, such a one as she hath daily and necessary use of, as being poor, as may appear by comparing this with Deuteronomy 24:12,13, and with other places. But this concerns not rich persons, nor superfluous raiment.
