And it came to pass, that He was traveling through the corn-fields on the Sabbath-day; and His disciples began to make the journey plucking the ears.

And the Pharisees continued to say to Him, Behold what they are doing on the Sabbath, which is not lawful.

And they were watching Him, if He will heal him on the Sabbath, that they might accuse Him.

And He says to them; Is it lawful to do good or to do evil on the Sabbath; to save life, or to kill? And they were silent.
