Here's an aspect of the march around Jericho that we seldom consider: At least one of those circuits was on the weekly Sabbath. They weren't laboring at a job or doing business, so I don't think it violated the Sabbath in any meaningful way. The only people who were carrying any burden were the priests, and their burden was shared.
