Who wrote the Bible? Joshua, Explained

Who wrote the book of Joshua?

Who really wrote the Book of Joshua? The honest answer: nobody knows for certain. But the clues buried inside the text itself tell a fascinating story. From Joshua’s own hand to later editors — possibly centuries apart — this is biblical detective work at its most compelling.

Who Wrote the Bible? — Series 2

The Pentateuch left us on a cliffhanger. Joshua is where things finally go down.

First — a quick recap

If you caught the last instalment, you’ll remember the Pentateuch — the first five books of the Bible — ends with Israel camped right on the edge of the Promised Land after 40 years of wandering in the desert. Moses is gone. The people are ready. And that’s exactly where Joshua picks up.

Think of it like the sequel that actually delivers on the setup.

So who wrote the book of Joshua?

Short answer: nobody actually knows. But don’t let that put you off — because the clues inside the text itself are genuinely fascinating, and scholars have been playing detective with them for centuries.

Joshua 24:26	Joshua himself is described as writing in “the Book of the Law of God.” So there’s a real possibility he authored at least part of this book. Evidence for Joshua as author.
Joshua 4:9	Twelve stones are set up and described as standing there “to this day” — a phrase that implies the writer is looking back from a later point in time. Suggests the text was written (or edited) after Joshua’s lifetime.
Joshua 15:63	The Jebusites are mentioned as still living in Jerusalem. David didn’t conquer Jerusalem until around 1010 BC — meaning this passage must have been written before that. Puts a rough upper limit on when at least part of the text was composed.

What does all that tell us?

Piecing it together, the most likely scenario is that Joshua wrote some of it, but the full text we have today was completed — or at least edited — sometime after his death, and before David took Jerusalem around 1010 BC. It’s a bit like a manuscript that got started by one person and finished by another.

But not everyone is satisfied with that. The debate runs further:

Theories two and three both suggest the book was written — or substantially reworked — much later, possibly drawing on older source material. The Babylonian exile theory in particular mirrors what we saw with the Pentateuch debate: a community in crisis, reaching back into their history to make sense of where it all went wrong.

The bottom line

The honest answer is still: we don’t know for certain. But the clues embedded in the text point to a layered story — parts written close to the events, parts shaped by later hands. 

Either way, Joshua is where the story of Israel stops being a promise and starts being a reality. That’s worth paying attention to.
