LOL...but Seriously...
please consider that for centuries Jews preserved the Sabbath the highest holy day in their calendar...zealous to the point they lost battles because they would not fight on it...
"The principal sources of our historical information about this ritual piety are the Apocryphal Books of the Maccabees and the works of Josephus Flavius. In I Maccabees (2:29-37), we find the following narrative about a Greek attack on the Jews:
The [Greeks] arose, suddenly, to fall upon [the Jews] on Shabbat, saying to them: How long will you refuse to obey the king . . . . And the men in their midst did not raise their hands to hurl a stone or to silence them . . . and they fell upon them on Shabbat and killed all those in the cave . . . about 1,000 people.
The deaths of 1,000 Jewish men, women, and children prompted Matthias and the Maccabees to respond. They decided, the text continues, that if they were again attacked on Shabbat, they would fight a defensive battle:
They said to one another: If we all act as our brothers have, and refuse to defend our lives and beliefs, we will shortly be destroyed. They decided on that day: Whosoever will attack us on Shabbat, we will fight back; we will not die like our brothers in the caves.
But, while the Jews now responded to attacks on Shabbat, they still refrained from responding to less imminent threats. Thus, the Syrian general Nicanor attempted to surprise the Maccabees by an attack on Shabbat (2 Maccabees 15:1-5), reasoning that the Jewish defenders would not begin to arm themselves until they actually came under attack on that day. He failed, but only because he lost the element of surprise for long enough to enable the defenders to reach their weapons."
A reformulation of the law was clearly required.
