Judaism is a monotheistic offshoot of Ur (Chaldean) pantheistic moon worship (Sīn).
Tradition, not archaeological record, teach that around 1800 B.C.E., Abram lived in the plain of Shinar, at Ur. Also according to Hebrew tradition, Abram left his homeland and stayed a while in Haran (also a center of cult moon worship) before settling in Canaan, because the “I Am / I [Cause] to Be” (YHWH), aka El-Shaddai (Almighty God) or just El or Elohim, i.e. “God(s)” had commanded him.
But the Chaldean god Sīn was also known in Ur as chief of the gods & creator of all things, and Sīn also was called El.
Moreover, Sīn was known as the father of Ishkur (aka Hadad)… or as Bible geeks might know him better: “Ba’al.” Lastly, in popular Hebrew/Canaanite religion (as evident from archaeology, 1200s B.C.E. to 500s B.C.E.), YHWH (El)—of Sīnai—was coupled with a consort, Asherah (NOVA).
While scholars like Michael Heiser assert that the pairing of YHWH and Asherah (Ashteroth) is heterodox to ancient Israelite belief, Heiser has to employ anachronism to make his assertion. Archaeological evidence indicates Israelite monotheism began after its polytheism. Again, from 12th Century B.C.E. to 500s C.E., we have record that Asherah was coupled with YHWH; and before that, Asherah was known as the Ugaritic, Athirat.
Athirat’s name itself is theorised by certain translators and commentators to be from the Ugaritic root ʾaṯr, ‘stride’, a cognate of the Hebrew root ʾšr, of the same meaning….Another primary epithet of Athirat was qnyt ʾilm[d] which may be translated as “the creatrix of the Gods“. In those texts, Athirat is the consort of the god ʾEl; there is one reference to the 70 sons of Athirat, presumably the same as the 70 sons of ʾEl. (Wikipedia)
In Syria, Athirat appears in the mythological texts from Ugarit and in a myth preserved in a Hittite adaptation. She is the consort of the resting chief god El and the mother of the gods. In the Hittite text, she appears as the wife of Elkunirsha, a transcription of the Semitic title “El, the owner of the earth.” (Encyclopedia.com)
Based on the above, & that ancient Hebrews held a lunar calendar with animal sacrifices, the Hebrew tradition for Abram’s “revelation” of God (in name & concept) was not all that new and not all that unique in Canaan. In likelihood, Abram did not bring any real difference in beliefs with him from Ur into Canaan.
It seems almost certain that the God of the Jews evolved gradually from the Canaanite El, who was in all likelihood the “God of Abraham”… If El was the high God of Abraham—Elohim, the prototype of Yahveh—Asherah was his wife, and there are archaeological indications that she was perceived as such before she was in effect “divorced” in the context of emerging Judaism of the 7th century BCE. (See 2 Kings 23:15.)
Seeing we have no historical date for Abram—the monotheism of the ancient Israelites was most probably a development that occurred over several hundred years after the traditional time that Abram brought a slightly modified moon worship with him to Canaan. That summary is in keeping with archaeology.
The victory stele of Pharaoh Merneptah, the son of Ramesses II, mentions a list of peoples and city-states in Canaan, and among them are the Israelites. And it’s interesting that the other entities, the other ethnic groups, are described as nascent states, but the Israelites are described as “a people.” They have not yet reached a level of state organization. So the Egyptians, a little before 1200 B.C.E., know of a group of people somewhere in the central highlands—a loosely affiliated tribal confederation, if you will—called “Israelites.” These are our Israelites…. Many scholars now think that most of the early Israelites were originally Canaanites, displaced Canaanites, displaced from the lowlands, from the river valleys, displaced geographically and then displaced ideologically. So what we are dealing with is a movement of peoples but not an invasion of an armed corps from the outside. A social and economic revolution, if you will, rather than a military revolution. And it begins a slow process in which the Israelites distinguish themselves from their Canaanite ancestors, particularly in religion…. These are pioneers in the hill country who are fleeing the urban centers, the old Canaanite cities, which are in a process of collapse. And in particular they are throwing off the yoke of their Canaanite and Egyptian overlords. They are declaring independence…. most archeologists today would argue that the United Monarchy was not much more than a kind of hill-country chiefdom. It was very small-scale (NOVA).
Ancient Israel’s moon god monotheism was just a spin-off, conveniently innovated to create a new highlands “tribe” of moon monotheists, who find referent in Semitic moon pantheism.
When the prophet Elias / Eliyah (meaning “Yahweh is my God”) stands on the mountain Carmel & tells the people to choose between Ba’al or YHWH (aka coopted Sīn), it’s like Eliyah is saying “is the father of Ba’al not higher than Ba’al?” Because Ba’al (Hadad) was worshipped as the god of rain / storm / thunder, Eliyah’s challenge of Ba’al in a time of drought & in the name of YHWH (coopted Sīn), was essentially to show that ‘father is greater than son.’ Hadad (Ba’al) was equated with the Greek god Zeus; the Roman god Jupiter, as Jupiter Dolichenus; the Hittite storm-god Teshub; the Egyptian god Set.
For the Tanakh to show YHWH (coopted Sin) asserting supremacy over Ba’al via the Elias account was an assertion of YHWH’s supremacy over every ANE god… albeit by using “fire from heaven,” which was attributed to the Babylonian/Assyrian Nusku, the son of Sin and brother of Ba’al.
Where do I see Jesus falling in with all of this? As JRR Tolkien said, “Christ is the myth that came true.” He showed up to show each and every ANE religion (esp. Judaism) how wrong they had gotten “God.” Jesus’ teachings destoy religion:
