“The Jews therefore said to him who was cured, ‘It is the Sabbath; it is not lawful for you to carry your bed.’ He answered them, ‘He who made me well said to me, “Take up your bed and walk.”’ Then they asked him, ‘Who is the Man who said to you, “Take up your bed and walk”?’ But the one who was healed did not know who it was, for Jesus had withdrawn, a multitude being in that place.” John 5:10-13.
“After this there was a feast of the Jews, and Jesus went up to Jerusalem. Now there is in Jerusalem by the Sheep Gate a pool, which is called in Hebrew, Bethesda, having five porches. In these lay a great multitude of sick people, blind, lame, paralyzed, waiting for the moving of the water. For an angel went down at a certain time into the pool and stirred up the water; then whoever stepped in first, after the stirring of the water, was made well of whatever disease he had.” John 5:1-4.
“And as Moses lifted up the serpent in the wilderness, even so must the Son of Man be lifted up, that whoever believes in Him should not perish but have eternal life.” John 3:14-15.
