You just make shit up. El was before Yaweh, long before. El and Yaweh is the same person. Lie to yourself all you want, have fun explaining to yourself how Jehovah (lol) was content with his people calling themselves Isa-EL-ites, or his promised land Isra-EL.
Let’s first look at the etymology of the name “Israel.” It is by no means a foregone conclusion as your source contends. Note the first two has to do with “fighting.”
“The etymology of the name “Israel” has not been explained satisfactorily.”
“This translation of the verbal element is based entirely on the popular etymologies cited, and is therefore by no means compelling. This obvious fact has led over the years to a wealth of proposed interpretations” (TDOT, vol. VI, pp. 399, 400).
HALOT gives five choices: a) to fight against Gn 32 29 Hos 12 4f ; b) same derivation but God as sbj., “El fights”, so Eissfeldt OLZ 58:331; c) to rule, prove oneself, be ruler (Noth 207ff); d) Arb. to shine (HBauer ZAW 51:83); e)to heal (Albright JBL 46:165ff.; 63:221 96 ) .
Let’s go to your second source Mark S. Smith: He makes a statement: “The original god of Israel was El.” He continues: “This reconstruction may be inferred from two pieces of information. First, the name Israel is not a Yahwistic name, but an El name…” “Second, Genesis 49:24-25 presents a series of El epithets separate from the mention of Yahweh in verse 18…”
So the evidence is quite flimsy. And do we know for certain who borrowed from whom? Did the writer borrow from the priests of Ugarit or vice versa?
Can you show ONE reference to what you said, one paper? One scholar? One piece of evidence...... just one? JUST ONE ?
While we are dealing with Mark S. Smith, do me a favor and get his book, The Origins of Biblical Monotheism. Israel’s Polytheistic Background and the Ugaritic Texts. It will acquaint you with the origin and development of monotheism in Israel. You will find “Mosaic Monotheism” is discussed on pp. 150-151.
