The King will say "I'm telling the solemn truth: Whenever you did one of these things to someone overlooked or ignored, that was me - you did it to me."

Matthew 25:34-40

Then the King will say to those sheep on his right, "Come, you who are blessed by my Father; take your inheritance, the Kingdom prepared for you since the creation of the world.  For I was hungry and you gave me something to eat, I was thirsty and you gave me something to drink, I was a stranger and you invited me in, I needed clothes and you clothed me, I was sick and you looked after me, I was in prison and you came to visit me."

Then those sheep are going to say, "Master, what are you talking about?  When did we ever see you hungry and feed you, thirsty and gave you drink?  And when did we ever see you sick or in prison and come to you?"  The King will say "I'm telling the solemn truth: Whenever you did one of these things to someone overlooked or ignored, that was me - you did it to me."
