Generalizing a lot here, but Jews and Christians interpret ambiguities within scripture very differently. Most Christians will try to maintain the spirit of the rule. Jews often view ambiguities as loopholes intentionally left by God. If the loophole wasn't mean to be there, God would have written it differently.

For a great example see https://en.wikipedia.org/wiki/Eruv . Look carefully and you'll see these in Jewish areas of NYC like Williamsburg.
