Deuteronomy 33:20-21

20About the tribe of Gad he said, “Blessed is the one who gives the people of Gad more land. They wait there like a lion. They can tear off an arm or a head.

21They chose the best land for themselves. Indeed, a commander’s piece of land was reserved for them. They were leaders of the people and did for Israel what the Lord considers fair and honorable.”
