I have often wondered about the city of Jericho, and how large it was and how long it would have taken the Israelis to walk around it 7 times on the 7th day.
So I thought I'd check it out.
Here's some of what I found.
"Within the upper wall was an area of approximately six acres, while the total area of the upper city and fortification system was 50% larger, or about nine acres." (So it was do-able to walk around it)
Based on the archaeologist’s rule of thumb of 200 persons per acre, the population of the upper city would have been about 1,200. However, from excavations carried out by a German team in the first decade of this century, we know that people were also living on the embankment between the upper and lower city walls. In addition, those Canaanites living in surrounding villages would have fled to Jericho for safety. Thus, we can assume that there were several thousand people inside the walls when the Israelites came against the city.
The people must have thought it funny though to have to march around the city once a day, for 7 days, then 7 times on the 7th day.
It is quite interesting to read see here
