Final answer:
In the book of Exodus, the two names for God are Elohim and Yahweh, with the latter becoming the exclusive name of God associated with the Hebrew people and their covenant.
Step-by-step explanation:
In the book of Exodus, the two names for God that are assigned to the patriarchal period and the Israelites during the exodus and beyond are Elohim and Yahweh. The name Elohim is associated with the more general term for God, while Yahweh is considered the personal name of God as revealed to Moses and is intimately associated with the Hebrew people and their covenant with God.
The Hebrew Bible emphasized the worship of Yahweh as the exclusive God of the Hebrews. During the Exodus, this worship grew in importance among the Hebrew people, which included the understanding of Yahweh as omnipotent and omnipresent. Yahweh was seen as a being who cared deeply for the Hebrew people, set apart from the capricious deities of neighboring cultures, and this distinction helped shape the emerging monotheistic Yahwist religion.
