"I was hungry, and you gave me food to eat. I was thirsty, and you gave me drink. I was a stranger, and you took me in. I was naked, and you clothed me. I was sick, and you visited me. I was in prison, and you came to me."

Or in Sydney Carter's version:

When I needed a neighbour
Were you there, were you there?
When I needed a neighbour
Were you there?
And the creed and the colour
And the name won't matter
Were you there?

I was hungry and thirsty
Were you there, were you there?
I was hungry and thirsty
Were you there?
And the creed and the colour
And the name won't matter
Were you there?...
