How many people lived in Old Testament Jericho?

Answer 1

During the Late Bronze Age, the time attributed in the Book of Joshua to the conquest of Jericho, archaeologists say that there was no city of Jericho, and therefore no inhabitants. However, they say there is some evidence of a possible small, unwalled village on the site of the city at this stage; if so the population would have been quite small. During the Israelite period, Jericho became a walled and gated city, as shown by 1 Kings 16:34, "In his[King Ahab] days did Hiel the Bethelite build Jericho: he laid the foundation thereof in Abiram his firstborn, and set up the gates thereof in his youngest son Segub, according to the word of the LORD, which he spake by Joshua the son of Nun." The population of a walled city was usually in the thousands.

Estimates suggest that Jericho had a population ranging from a few hundred to a few thousand individuals during the Old Testament period. The city's population size likely fluctuated over time due to various factors such as warfare and economic conditions.
