Numbers chapter 9

After reading chapter 9:

*The book of Numbers began at the second month of the second year. Chapter 9 takes us back to the first month of that year to tell us that the Israelites celebrated the passover like they were supposed to, on the 14th day at twilight. However, it seems that some people were not able to celebrate because they were made unclean by a dead body. Moses consulted Yahweh, who said anyone who hadn't been able to observe it the first month must do so on the 14th day of the second month, in the same way they would have observed it  in the first month. I find it interesting that the 14 th day of a lunar month is usually a full moon.  Any one who failed to celebrate the passover was excommunicated.

*This chapter also refers back  to the day the tabernacle was set up, which, according to Exodus, was the first day of the first month of the second year. We are again told about the cloud that came to rest over the tabernacle and how the Israelites moved when it moved, no matter how long or short the time was.
