Step-by-step explanation:
The four names of God in the Old Testament selected for study in this unit are a) Adonai, b) Yahweh, c) El Lord of Hosts, and d) Elohim Lord. The student's question seems to be focused on the development and understanding of the concept of monotheism and the transition from henotheism in the ancient Hebrew religious practices, centered around the worship of Yahweh.
The Hebrews initially worshipped a variety of deities, but over time, the exclusive worship of Yahweh became central to their identity, evolving into monotheism. This was shaped by geopolitical pressures and the belief in Yahweh's omnipotence and exclusivity, particularly post the Assyrian conquest and during the formation of early Judaism. The Yahwist religion embodied these changes, and eventually the exclusive god of the Hebrews was seen as the only true god, with other gods viewed as illusory.
