Yahweh, prior to becoming Yahweh the national god of Israel and taking on monotheistic attributes in the 6th century BCE, was a part of the Canaanite pantheon in the period before the Babylonian captivity. Archeological evidence reveals that during this time period the Israelites were a group of Canaanite people. Yahweh was seen as a war god, and equated with El. Asherah, who was often seen as El's consort, has been described as a consort of Yahweh in numerous inscriptions.[1] The name Yahwi may possibly be found in some male Amorite names.[2] Yahu may be found in a place name.
Smith's 1863 A Dictionary of the Bible says that "Yahweh" is possible because shortening to "Yahw" would end up as "Yahu" or similar.
