Final answer:
Abraham influenced the Israelites' way of life through the Covenant with Yahweh, the modification of the Covenant by Moses, and the establishment of monotheism.
Step-by-step explanation:
Abraham had a significant influence on the way the Israelites lived through his agreement to the Covenant with the God Yahweh. This Covenant stated that the Israelites would receive a promised land and prosperity in return for their devotion, worship, and circumcision of all Hebrew males.
Furthermore, Moses, a prophet, modified the Covenant to include specific rules of behavior, such as abiding by the 10 Commandments. The Israelites' adherence to these commandments was essential for their prosperity in the promised land, establishing a code of ethics for righteous living within their community.
Abraham's role in establishing monotheism among the Israelites also greatly influenced their way of life. He entered into a covenant with Yahweh, setting the foundation for Hebrew monotheism, which continued to take shape through the emergence of Moses and the exodus from Egypt.
