and they did--in the Wilderness of Sinai at evening of the fourteenth day of the first month. The People of Israel did it all just as GOD had commanded Moses.
But some of them couldn't celebrate the Passover on the assigned day because they were ritually unclean on account of a corpse. So they presented themselves before Moses and Aaron on Passover
and told Moses, "We have become ritually unclean because of a corpse, but why should we be barred from bringing GOD's offering along with other Israelites on the day set for Passover?"
"Tell the People of Israel, If one or another of you is ritually unclean because of a corpse, or you happen to be off on a long trip, you may still celebrate GOD's Passover.
"But a man who is ritually clean and is not off on a trip and still fails to celebrate the Passover must be cut off from his people because he did not present GOD's offering at the set time. That man will pay for his sin.
"Any foreigner living among you who wants to celebrate GOD's Passover is welcome to do it, but he must follow all the rules and procedures. The same procedures go for both foreigner and native-born."
The day The Dwelling was set up, the Cloud covered The Dwelling of the Tent of Testimony. From sunset until daybreak it was over The Dwelling. It looked like fire.
If the Cloud stayed only from sunset to daybreak and then lifted at daybreak, they marched. Night or day, it made no difference--when the Cloud lifted, they marched.
It made no difference whether the Cloud hovered over The Dwelling for two days or a month or a year, as long as the Cloud was there, they were there. And when the Cloud went up, they got up and marched.
