"If I testify about myself, my witness is not valid.

 5:1-9 After this there was a Feast of the Jews, and Jesus went up to Jerusalem. In Jerusalem, near the sheepgate, there is a bathing-pool with five porches, which was called in Hebrew, Bethzatha. In these porches there lay a crowd of people who were ill and blind and lame and whose limbs were withered [waiting expectantly for the moving of the water. For an angel of the Lord came down into the pool every now and then and disturbed the water; so the first person to go in after the disturbing of the water regained his health from any illness which had him in its grip]. There was a man there who had been ill for thirty-eight years. When Jesus saw him lying there, and since he knew that he had already been there for a long time, he said to him: "Do you want to be made well?" The sick man answered: "Sir, I have no one to hurry me into the pool when the water is disturbed; so, while I am on the way, someone gets down before me." Jesus said to him: "Get up! Lift your bed! and walk!" And the man was made well, and he lifted up his bed and walked.
