Ofra Rabbi Oks Arabs To Build Jewish Homes on Sabbath
Jewish law prohibits working on the Sabbath except in special cases or if lives would be put at risk by not working. Non-Jewish workers may work on the Sabbath, but Jews generally may not tell them to do so on their behalf. In this case, Rabbi Gisser explained that the commandment to settle all of Israel overrides the prohibition.
However, other rabbis differ from his decision and say that preservation of the Shabbat is the most important consideration if there is not a direct threat to life.
