'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.
Now these are the nations which the Lord left, to test Israel by them (that is, all who had not experienced any of the wars of Canaan;
only in order that the generations of the sons of Israel might be taught war, those who had not experienced it formerly).
The Israelites, apart from Benjamin, rallied 400,000 armed men, every one an experienced warrior.
