Moses’ right hand man and heir, Joshua was the leader who led the Israelites into Canaan after their 40 years of exile in the Sinai desert.
The major conflict recorded by the Bible in this period – which was, in all fairness, an invasion and conquest of Canaan by the Israelites – was the battle of Jericho. The Israelites under Joshua laid siege to this town (which is one of the oldest continually occupied human settlements in the world). The Israelites spent a week carrying the Ark of the Covenant around the city while holding horns in front of it – on the seventh day, they blew the horns, and the walls came down. Stripped of their greatest defence, the Canannites of Jericho well slaughtered and the town razed – only a turncoat who had assisted the Israelites (and her family) was left alive.
