'Divisions' in the Bible

This is the same Aaron and Moses to whom the LORD said, "Bring the Israelis out of the land of Egypt by their tribal divisions."

WhenPharaoh won't listen to you, I'll let loose my power upon Egypt. I'll bring out my tribal divisions my people the Israelis from the land of Egypt with great acts of judgment.

""You are to observe the Festival of Unleavened Bread, since on this very day I brought your tribal divisions from the land of Egypt. You are to observe this day from generation to generation as a perpetual ordinance.

At the end of 430 years, to the very day, all the tribal divisions of the LORD went out from the land of Egypt.

And on that very day, the LORD brought the Israelis out of the land of Egypt by their tribal divisions.
