Yod He Wav He, the tetragramaton, no one on Earth knows where the vowel placements go and thus no one knows how to decipher the unspoken name of GOD. Yahweh is a considered a good guess. Muslim Scholars have shown YHWH can also be deciphered as ALLAH swt, but again all guesswork. Let's for the sake of argument agree that Yahweh is the God worshipped by the Israelites.
From information you provided..
The Moabite stone 930B.C mentions the Moabites invoked their god, Chemosh who granted them victory over the Israelites and Yahweh, they offered the slaughtered women and girls to the goddess Ashtar, linked to the god Chemosh.
Could you tell me about Yahweh, origins etc? I ask because we know that following revelation received directly from GOD, (He spoke to all of those assembled) they eventually turned away from Monotheism in favour of Polytheism.
The plurality of deities was such that in an inscription by Sargon II, who completed the conquest of the kingdom of Israel in the late 8th century BCE, the Assyrian king mentioned that after capturing the capital Samaria, his troops brought back “the (statues of) gods in which (the Israelites) had put their trust.”
In the kingdom of Israel, as Hosea 8 and 1 Kings 12:26-29 relate, Yahweh was often worshipped in the form of a calf, just like the god Baal was. (1 Kings 12:26-29 explains that Jeroboam made two calves, for the sanctuaries at Bethel and Dan, so the people could worship Yhwh there and wouldn’t have to go all the way to Jerusalem. Ergo, in northern Israel at least, the calves were meant to represent Yhwh.)
Jeremiah speaks about the many gods of Judah, which are as numerous as the streets of a town. There was certainly worship a female deity, Asherah or the "Queen of Heaven” Then there was the storm god, Hadad, (Baal).
In Judges 11:24, Jephtah tries to resolve a territorial dispute by telling the Ammonites that the land of Israel had been given to the Israelites by Yhwh, while their lands had been given to them by their god Chemosh ("Will you not take what your god Chemosh gives you? Likewise, whatever Yhwh our god has given us, we will possess.")
So tell me about the origins of Yahweh and give your thoughts on why you think highly respected and learned Jewish Scholars, past and present have said Jews and Muslims, (from 7th Century onwards) worship the same ALLAH swt, it's not like Jews are living in Muslim lands or have any need to appease us.
Concealing the name of God
Concealing the name of God was not only a custom, it was also made a law.
The sages quoted, "This is my name for ever, and this is my memorial unto all generations" (Ex. iii. 15). Here the word "le-'olam" (forever) is written defectively, being without the "waw" for the vowel "o," which renders the reading "le-'allem" (to conceal; Ḳid. 71a).
Forty years prior to the destruction of the Temple, the priests ceased to pronounce the Name (Yoma39b). From that time the pronunciation of the Name was prohibited. "Whoever pronounces the Name forfeits his portion in the future world" (Sanh. xi. 1).
30 AD to 70 AD.
Abba Saul (2d cent.) condemned the profanation of the Tetragrammaton by classing those "that speak the Name according to its letters," with those who have no part in the future world (Sanh. x. 1); and according to 'Ab. Zarah 17b, one of the martyrs of Hadrian's time, Hananiah b. Teradion, was burned at the stake because he so uttered the Name.
The view that prayer is more effectual if the name of God is pronounced in it as it is written caused the scholars of Kairwan to address a question in the eleventh century to Hai Gaon with reference to the pronunciation of the Shem ha-Meforash, to which he answered that it might not be uttered at all outside the Holy Land (Hai Gaon, "Ṭa'am Zeḳenim," p. 55; see Löw, "Gesammelte Schriften," i. 204).
Because Hebrews dropped their 'ayins', to keep from saying God's name, hence we have "y'shua." Also spelled Yeshua, for which we have in Greek, "Iēsous" and "Isus." These are corruptions of the names that begin with "Yah."
Thirteen theophoric names with "Yeho" have corresponding forms where the letters eh have been omitted. There is a theory by Christian Ginsburg that this is due to Hebrew scribes omitting the "h", changing Jeho (יְהוֹ) into Jo (יוֹ), to make the start of "Yeho-" names not sound like an attempt to pronounce the Divine Name.

Yahwah
A note on the words hawah and hayah.
Quote from pages 217 and 218 of the Brown-Driver-Briggs. Ref # 3068-69 on page 217.
Brown-Driver-Briggs on page 218 states that, "Many recent scholars explain יהוה as Hiph. of הוה equals היה "
הוה hawah / HWH is hawah.
היה hayah / HYH is hayah.
Note that the vowels are all " a."
יהוה Yahwah
The vowels are "a" in the Brown-Driver-Briggs, the NIV Exhaustive Concordance, and the Strong's Exhaustive Concordances.
The name Yahwah is from the Aramaic, not the Hebrew.
The e vowel was introduced by the Masoretes in the 6 century AD.
Jewish scholars of the 6th–10th centuries AD who contributed to the establishment of a recognized text of the Hebrew Bible, and to the compilation of the Masorah.
