'On the Sabbath' in the Bible

And they journey into Capernaum. And, straightway, on the Sabbath, entering into the synagogue, he began teaching;

And it came to pass, that he, on the Sabbath, was passing through the cornfields, and his disciples began to be going forward, plucking the ears of corn.

And, the Pharisees, were saying, - See! why are they doing, on the Sabbath, what is not allowed?

and they were narrowly watching him, whether, on the Sabbath, he would cure him, that they might accuse him.

and saith unto them - Is it allowed, on the Sabbath, to do good, or to do evil? To, save, life, or, to slay? but they remained silent.
