As we know there have been many proposals as to the origins of the god and name YHWH. The folk etymology of Ex 3 aside, there have been a number of suggested roots, many of which seem to be well argued and not without possibility. However, of particular interest to me are those proposals consistent with the fairly well agreed upon south-eastern origins of the cult. The Kennite Hypothesis, as it is often called, uses OT and other epigraphic evidence to conclude the cult of YHWH was imported north via traders from Arabia. If this is correct it seems logical to seek a proto-Arabic root behind the name of the deity. A number of scholars have suggested HWY as that root.
The Arabic root HWY has three meanings. 1. To be Passionate/Jealous, desirous 2. to fall 3. to blow.
2 and 3 both make sense as weather terms. And the well known storm god aspects of YHWH make this a very attractive suggestion. The falling rain and wind associations would explain many aspects of the theophanic description of YHWH and why he is depicted as in constant struggle with the indigenous storm god Baal.
Even more, the first definition "Passionate" may go a long way in explaining declarations like that at EX 34:14, and Deut 5:7,9
For you must not worship any other god, because YHWH, whose name is Impassioned, is an impassioned God.
5:7You shall have no other gods besides Me… 5:9 You shall not bow down to them or serve them. For I YHWH your God am an impassioned God….
This may also further explain the often-repeated analogy of a husband/wife jealousy in describing the relationship of YHWH with his worshipers. Also, the use of adultery as the metaphor of worship of other deities. This one root word having multiple meanings offers a parsimonious solution to a number of disparate aspects of the YHWH character. To take it a step further it may explain the earliest beginnings of monolatry/monotheism. This god whose very name means 'passionately jealous' demanded exclusive commitment in the eyes of his priests.
I find this proposal to be attractive and persuasive in its explanatory power and its recognition of the Kennite hypothesis.
