The Religion Guy poses this complex historical question himself instead of the customary answer to an item posted via “Send Your Questions In” -- new submissions very much welcomed.

There’s been important debate on this issue recently, and a new book proposes sweeping reinterpretation of the Old Testament depiction of Israel’s “Conquest” of the Holy Land under Joshua. More on that below.

Richard Dawkins, a fervent foe of religion, indicts the biblical God for inciting “genocide” in the Bible’s conquest passages and verses like Deuteronomy 20:16-18 that direct believers to wipe out neighboring populations. Many U.S. Jews and Christians frankly admit this material is troubling.

Let’s begin with three standard Jewish commentaries on those Deuteronomy verses.

“Pentateuch & Haftorahs,” a classic Orthodox compilation by J.H. Hertz, Britain’s longtime chief rabbi, observes that Joshua informed Canaanites before the invasion so they could flee bloodshed, offered peace to all, and only waged combat if they insisted on it. (That was relatively humane for violent times 3,000 years ago.)

The quest for a homeland, the commentary observes, is part of all human history including most European nations. Israel added to that the “ethical justification” of countering Canaan’s “depravity,” for instance human sacrifice. Moreover, “the whole moral and spiritual future of mankind was involved.”
