Final answer:
Moses allocated the land east of the Jordan River to the tribes of Reuben, Gad, and the half-tribe of Manasseh. This was part of their journey after leaving Egypt, known as the Exodus, during which they agreed to worship Yahweh and abide by his laws, including the Ten Commandments.
Step-by-step explanation:
Moses divided the land east of the Jordan among the tribes of Reuben, Gad, and the half-tribe of Manasseh before the children of Israel crossed the Jordan River into Canaan. This division of land took place after their Exodus from Egypt, where they had been enslaved for generations. Moses, acting under the direction of God, assigned these territories to them as per Biblical accounts.
According to the Hebrew Bible and religious teachings, Moses played a significant role in leading the Hebrews out of Egypt, across the Sinai desert, and into Canaan. During this journey, they agreed to exclusively worship Yahweh and follow his laws, which included the Ten Commandments. While the biblical narrative describes Moses's leadership and the allocation of lands among the tribes east of the Jordan River, archaeological records and scholarly research have debated the historicity and scale of these events.
