Notes: "YHWH (Yahweh, Jehovah or יהוה in the original Hebrew) is the name of (one of) the god(s) of Abraham that appears in the Hebrew Bible (Tanakh), and the name for the monotheistic God that the Jews and Christians would later worship. YHWH does not appear to be a Canaanite god, but instead an Edomite one." Source: Rational Wiki.
The origins of the god YHWH are murky, but it appears that the ancient Israelites may have adopted his worship after contact with the Edomites [?] and incorporated him into their existing pantheon. According to the Rational Wiki, "[evidence] found in the Canaanite city of Ugarit suggests the ancient Israelites practiced a polytheistic (1) North-west Semitic religion, with a creator god, El. Yahweh was associated with El, and became the 'national god' of the Hebrews."
