Matthew 25:35
For I was hungry and you gave me food, I was thirsty and you gave me drink, I was a stranger and you welcomed me. The basis of the blessing: concrete acts of mercy — food for the hungry, drink for the thirsty, welcome for the stranger. The I was hungry and you gave me communicates the identification of the King with those who received the mercy. The sheep who are receiving the inheritance did not know they were serving the King.
