John Gill Commentary Matthew 25:43

"I was a stranger, and ye took me not in; naked, and ye clothed me not; sick, and in prison, and ye visited me not." — Matthew 25:43 (ASV)

I was a stranger, and you took me not in
Did not take the poor members of Christ into their houses, and take care of them in their families, when they were obliged to flee from their places of abode, or wandered about preaching the Gospel; and who must have perished in the streets, if others, that bore the Christian name; had not been more compassionate than they:

naked, and you clothed me not: sick and in prison, and you visited me
not :
their conduct, behaviour, and character, are just the reverse of the righteous, and therefore it is no wonder that their sentence is different.
