'On the Sabbath' in the Bible

At that time Jesus went through the grain fields on the Sabbath. And his disciples were hungry, and they began to pluck off heads of grain and eat [them].

But [when] the Pharisees saw [it], they said to him, "Behold, your disciples are doing what it is not permitted to do on the Sabbath!"

Or have you not read in the law that on the Sabbath the priests in the temple violate the sanctity of the Sabbath and are guiltless?

And behold, [there was] a man who had a withered hand, and they asked him, saying, "Is it permitted to heal on the Sabbath?" in order that they could accuse him.

But he said to them, "What man will there be among you who will have one sheep and if this one fell into a pit on the Sabbath, will not take hold of it and lift [it] out?

Then to what degree [is] a man worth more than a sheep? So then, it is permitted to do good on the Sabbath."
