The first time.
I’m reading Joshua and following this webpage:
1. The Israelites crossed the Jordan, then;
2. Camped at Gilgal (the webpage says the Tabernacle was set up there, but this must be deduced from the word “encamped” in the verse Josh. 4:19. It was established in the wilderness that when they were to encamp they were to set up the tabernacle.), then;
3. Conquered Jericho, then;
4. Conquered Ai (it took 2 tries); then
5. Joshua built the altar at Mt. Ebal (actually on the plain between Mt. Ebal and Mt. Gerizim) and read the law of Moses to the people (Josh 8:30-35). Some of the readings from this event are probably found in Deuteronomy (See the webpage link) … but maybe the whole Pentateuch was read. This site has been tested and functions as a natural amphitheater.
Joshua’s altar looks like it was built on the site of Abraham’s and Jacob’s altars by the oaks of Moreh by Shechem. This closes the loop of the prophetic blessing that God gave Abraham there in the first place and allows Joshua to expound what character that blessing is to take.
6. I’m skipping stuff …
7. I think the following verse is saying that the Tabernacle was set in place at Shiloh once the conquest of Canaan was complete:
“Then the whole congregation of the sons of Israel assembled themselves at Shiloh, and set up the tent of meeting there; and the land was subdued before them.” Joshua 18:1
8. In the last year of Joshua’s life the tabernacle was moved from Shiloh to the Mt. Ebal site (Josh. 24:25-28).
