“On the first day of the first month you are to set up the tabernacle, the tent of meeting.

¶ Organizing the Census of the Israelites Now the LORD spoke to Moses in the tent of meeting in the desert of Sinai on the first day of the second month of the second year after the Israelites departed from the land of Egypt. He said:

And they observed the Passover on the fourteenth day of the first month at twilight in the desert of Sinai; in accordance with all that the LORD had commanded Moses, so the Israelites did.

Whenever the cloud was taken up from the tabernacle, then after that the Israelites would begin their journey; and in whatever place the cloud settled, there the Israelites would make camp.
