'On the Sabbath' in the Bible

At that time Jesus went on the sabbath through the grainfields; and his disciples were hungry, and began to pluck the ears of grain, and to eat.

But the Pharisees, seeing it, said to him, Lo! thy disciples are doing that which it is not lawful to do on the sabbath.

Or have ye not read in the Law, that on the sabbaths the priests in the temple profane the sabbath, and are blameless?

And, lo! there was a man having a withered hand. And they asked him, saying, Is it lawful to heal on the sabbath? that they might accuse him.

And he said to them, Who of you that owneth one sheep, if it fall into a pit on the sabbath, will not lay hold of it, and lift it out?

Of how much more worth now is a man than a sheep! So then it is lawful to do well on the sabbath.
