But that's just for the Holy of Holies. At the time of Herod's Temple there were several "courtyards" designed for the purpose of keeping certain folks out of the Temple proper.
This of course created a disparity of law based on class or sex.
Ergo, there were more than one system of laws even in ancient Israel!
Canada, by the way, in case you missed it, ain't Israel!
Sorry, there was still only one set of laws, even if that system discriminated against women and gentiles. (And being as how God handed down the ceremonial laws, I don't think that cries of "discrimination!" are really relevant or appropriate. He has a right to dictate how He wants to be worshipped.)
And no, I didn't miss the fact that Canada is not ancient Israel. However, I am suggesting that when God said that they should have one law for everyone, He was implying that that was the way to make sure that justice was practiced uniformly. I am suggesting that He intended that as a model for how nations should behave. Even Canada.
