'On the Sabbath' in the Bible

On the Sabbath He was passing through the wheat fields, and His disciples started to make a path by pulling off the wheat heads.

So the Pharisees were saying to Him, "Just look! Why are they doing on the Sabbath what it is against the law to do?"

And they kept closely watching Him, to see whether He would cure him on the Sabbath, to get a charge to bring against Him.

Then He asked them, "Is it right to do people good on the Sabbath, or to do them evil, to save life or to take it?" But they had nothing to say.
