When two commandments conflicted, one was considered to overrride the other. For instance, the Rabbis, the first Christians (obviously Jews) and almost certainly the Pharisees agreed that the comandments to do
good and to save life override the Sabbath, so if someone is in danger or seriously ill, itbecomes a meritorious
act to
help them on the Sabbath, even if that involves working. The author of the 'Damascus Covenant', on the other hand, took the opposite view; if a
man falls into a well or a fire on the Sabbath, you must not use a rope or a ladder or another utensil to pull them out. During the
Roman period, the requirement to have the
Temple tax paid in pure silver was clearly considered to override the ban on images, but the situation seems to have been reversed at the beginning of the First Revolt, given that the new government promptly started minting its own kosher shekels, without images.
