John 5
16 Ref And for this reason the Jews were turned against Jesus, because he was doing these things on the Sabbath.
17 Ref But his answer was: My Father is still working even now, and so I am working.
18 Ref For this cause the Jews had an even greater desire to put Jesus to death, because not only did he not keep the Sabbath but he said God was his Father, so making himself equal with God.
