'Experienced' in the Bible

That entire generation passed away; a new generation grew up that had not personally experienced the Lord's presence or seen what he had done for Israel.

These were the nations the Lord permitted to remain so he could use them to test Israel -- he wanted to test all those who had not experienced battle against the Canaanites.

He left those nations simply because he wanted to teach the subsequent generations of Israelites, who had not experienced the earlier battles, how to conduct holy war.

The men of Israel (not counting Benjamin) had mustered four hundred thousand sword-wielding soldiers, every one an experienced warrior.
