Matthew 25:40
And the King will answer them: truly, I say to you, as you did it to one of the least of these my brothers, you did it to me. The identification of the King with the least of these my brothers: the mercy shown to the hungry, thirsty, stranger, naked, sick, and imprisoned was mercy shown to the Son of Man himself. The least of these my brothers are the most vulnerable members of the community — and through them, the King himself was served.
