'On the Sabbath' in the Bible

Then they went into Capernaum, and right away He entered the synagogue on the Sabbath and began to teach.

On the Sabbath He was going through the grainfields, and His disciples began to make their way picking some heads of grain.

The Pharisees said to Him, “Look, why are they doing what is not lawful on the Sabbath?”

In order to accuse Him, they were watching Him closely to see whether He would heal him on the Sabbath.

Then He said to them, “Is it lawful on the Sabbath to do what is good or to do what is evil, to save life or to kill?” But they were silent.
