'On the Sabbath' in the Bible

Now because Jesus was doing these things on the Sabbath, the Jewish leaders began persecuting him.

However, because Moses gave you the practice of circumcision (not that it came from Moses, but from the forefathers), you circumcise a male child on the Sabbath.

But if a male child is circumcised on the Sabbath so that the law of Moses is not broken, why are you angry with me because I made a man completely well on the Sabbath?

Then, because it was the day of preparation, so that the bodies should not stay on the crosses on the Sabbath (for that Sabbath was an especially important one), the Jewish leaders asked Pilate to have the victims' legs broken and the bodies taken down.
