Give to him that asks you, and from him that would borrow of you turn not away.
All Commentaries on Matthew 5:42 Go To Matthew 5
John Chrysostom
AD 407
These last are less than what went before; but marvel not, for this He is ever wont to do, mingling the small with the great. And if these be little in comparison with those, let them hearken, who take the goods of others, who distribute their own among harlots, and kindle to themselves a double fire, both by the unrighteous income, and by the pernicious outlay.
But by borrowing, here, He means not the compact with usury, but the use merely. And elsewhere He even amplifies it, saying that we should give to them, from whom we do not expect to receive.
