Welcome to “Ehrman Errs,” a blog series devoted to using our conversational AI to refute each alleged biblical contradiction that is posed in the article on Bart Ehrman’s website: 50 Contradictions in the Bible: The Biggest, Most Shocking Differences.
Today’s alleged contradiction:
#40 – How Many Men Were in the Ambush Against Ai?
In Joshua 8, a numerical error arises concerning the ambush Joshua planned against the city of Ai. In verse 3, Joshua selects 30,000 warriors for the ambush, clearly distinguishing this group from those engaged in the direct attack. However, in verse 12, the text states that only 5,000 men were placed in ambush. The inconsistency between these two numbers is further complicated by verses 9 and 12, which indicate there was only one ambush force hidden west of the city.
How Does Ehrman Err?
Bart Ehrman points to what seems on the surface like a contradiction in Joshua 8, but when we look more closely — both at the literary structure and at the ancient Hebrew narrative style — the alleged discrepancy dissolves.
1. The Text Itself
- Joshua 8:3 (ESV) — “So Joshua and all the fighting men arose to go up to Ai. And Joshua chose thirty thousand mighty men of valor and sent them out by night.”
- Joshua 8:12 (ESV) — “He took about five thousand men and set them in ambush between Bethel and Ai, on the west side of the city.”
At first reading, these seem to refer to two different numbers for what appears to be the same ambush. But a careful reading reveals that they do not refer to the same group.
2. Understanding Hebrew Narrative Style and Structure
Ancient Hebrew narratives often give a summary statement and then introduce detail or parenthetical elaboration later (compare Genesis 2 expanding Genesis 1). In Joshua 8, the flow of the story moves between the overall military plan and specific tactical details.
According to the Precept Austin commentary on Joshua 8, verse 3’s 30,000 soldiers were “the larger detachment sent out by night,” while verse 12’s 5,000 were a smaller ambush unit deployed later between Bethel and Ai to block reinforcements (see PreceptAustin.org, Joshua 8 Commentary).
“The second contingent was the main army… The third contingent was another ambush numbering 5,000 men who were positioned between Bethel and Ai.” – PreceptAustin Joshua 8 Commentary
Thus, rather than one contradictory count, there were two separate ambushes as part of one strategic operation — a common practice in ancient warfare.
3. Corroboration from Scholarly Commentaries
Commentators such as Stephen Grant and George Bush (quoted in the same Precept Austin resource) note that if we treat verses 10–13 as a parenthesis, giving logistical detail rather than chronological succession, there is no contradiction. The 30,000 men were sent out first as the main ambush force by night, and then Joshua later stationed the 5,000 as a tactical reinforcement between Bethel and Ai.
“Verse 11 provides details of the troop movements between v. 3, when Joshua began the preparations, and v. 10, when they moved on the following morning.” – What the Bible Teaches – Joshua, cited on Precept Austin
4. The Strategic Logic
Here’s how the layout likely looked:
- Main Force (Joshua and the elders) — camped north of Ai (Joshua 8:11).
- First Ambush (30,000) — sent west of Ai (Joshua 8:3–9).
- Second Ambush/Rear Guard (5,000) — placed between Bethel and Ai to block reinforcements (Joshua 8:12–13).
Modern military scholars would call this a multi-tiered ambush, where deception and containment forces are used together. Joshua’s plan was brilliant; nothing in the text suggests numerical inconsistency once we recognize that these are two different ambush detachments.
5. Theological Application — Unity Between God’s Word and Truth
There is no contradiction in God’s Word because, as 2 Timothy 3:16 says, “All Scripture is breathed out by God and profitable for teaching, for reproof, for correction, and for training in righteousness.”
Jesus Himself affirmed, “Your word is truth” (John 17:17).
Thus, any apparent contradiction invites deeper study, not dismissal. As Proverbs 30:5 reminds us:
“Every word of God proves true; he is a shield to those who take refuge in him.”
6. Conclusion
When taken carefully:
- Joshua 8:3 refers to the main ambush force (30,000 men).
- Joshua 8:12 refers to a smaller tactical detachment (5,000 men), likely a secondary ambush.
- The parenthetical structure of verses 10–13 clarifies the movement and purpose of each contingent.
Therefore, there is no contradiction — only complementary details of a complex military maneuver that reveal Joshua’s divinely inspired wisdom and obedience to God’s instruction:
“See, I have given into your hand the king of Ai, and his people, his city, and his land.” (Joshua 8:1)
In short, what Ehrman considers an inconsistency actually showcases the richness of ancient Hebrew narrative and the depth of divine order behind Joshua’s campaign.
