Lord of the Sabbath

My family and I were reading through Joshua 6 yesterday, and it struck us that it was on the seventh day, presumably the Shabbat, when Israel marched around Jericho seven times (presumably a bit longer than the Pharisees' Sabbath walk) and conquered Jericho. 

In other words, as Jesus told us, the Sabbath is for man, not man for the Sabbath, and He is Lord of the Sabbath.
