'On the Sabbath' in the Bible

This is why the Jews were persecuting Jesus, because He persisted in doing such things on the Sabbath.

Then Moses gave you the rite of circumcision -- not that it had its origin with Moses but with your earlier forefathers -- and you circumcise a male child even on the Sabbath.

Well, if a male child undergoes circumcision on the Sabbath, to keep the law of Moses from being broken, are you angry with me for making a man perfectly well on the Sabbath?

Now it was on the Sabbath when Jesus had made the clay and caused the man's eyes to see.
