Most assuredly I tell you, we speak that which we know, and testify of that which we have seen, and you don't receive our witness.

 Take the case of journeying on the Sabbath. Exodus 16:29 says: "Remain every man of you in his place; let no man go out of his place on the seventh day." A Sabbath day's journey was therefore limited to two thousand cubits, that is, one thousand yards. But, if a rope was tied across the end of a street, the whole street became one house and a man could go a thousand yards beyond the end of the street. Or, if a man deposited enough food for one meal on Friday evening at any given place, that place technically became his house and he could go a thousand yards beyond it on the Sabbath day. The rules and regulations and the evasions piled up by the hundred and the thousand.
