When Joshua had let the people go - The author of this book is giving here a history of the people, from the division of the land by Joshua to the time in which the angel speaks. Joshua divided the land to them by lot; recommended obedience to God, which they solemnly promised: and they continued faithful during his life, and during the lives of those who had been his contemporaries, but who had survived him. When all that generation who had seen the wondrous works of God in their behalf had died, then the succeeding generation, who knew not the Lord - who had not seen his wondrous works - forsook his worship, and worshipped Baalim and Ashtaroth, the gods of the nations among whom they lived, and thus the Lord was provoked to anger; and this was the reason why they were delivered into the hands of their enemies. This is the sum of their history to the time in which the angel delivers his message.
