'Tribes of Israel' in the Bible

However, if a single trumpet is blown, then the leaders, heads of the tribes of Israel, shall gather themselves to you.

Then Moses spoke to the leaders of the tribes of the Israelites, saying, “This is the thing which the Lord has commanded:

A thousand [fighting men] from each tribe of all the tribes of Israel you shall send to the war.”

So Moses gave the command concerning them to Eleazar the priest, and to Joshua the son of Nun, and to the leaders of the fathers’ households of the tribes of the Israelites.
