What can we learn from bringing all these questions about their journey together in regards to the 7th Day Sabbath?

Answer From The Annual Reading Schedule - Week 34 Notes For Numbers: On the 20th, 21st, and 22nd of the 2nd month they were not resting – they were on a journey seeking out a resting place. This is the biggest evidence, in my opinion, that the 7th Day Sabbath is a continual 7 day cycle and not a cycle that restarts every month based upon the new moon (otherwise known as "Lunar Sabbath"). I do not see how Lunar Sabbath doctrines are possibly correct because they were on a journey on both the 21st and the 22nd.
