What does the first commandment have to do with monotheism?

The first commandment, which states, "You shall have no other gods before me," underscores the principle of monotheism by affirming the belief in a single, sovereign God. It establishes a clear distinction between the worship of one true God and the idolatry of multiple deities, highlighting the expectation of exclusive loyalty and devotion. This foundational commandment serves as a cornerstone for the Abrahamic faiths, reinforcing the idea that God is not only unique but also the sole object of worship.
