Thanks for clarifying. I probably would go further and say that Biblical oral culture was not constant over time - finally settling at least part of the Old Testament after the Babylonian exile. Like this question:
Exodus 6:2-3 tells us that God says “I am Yahweh. I appeared to Abraham, Isaac, and Jacob, as God Almighty (El Shaddai), but by my name [Yahweh] I did not make myself known to them.”
However, this appears to be… well not true.
Only one time did God present himself as El Shaddai to Abraham for example (in Genesis 17:1- Hebrew Concordance: šad·day -- 28 Occurrences). There are two other occurrences in Genesis where Isaac blesses Jacob with the blessings of God Almighty (Gen 28:3) and God introduces himself personally to Jacob as God Almighty (Gen 35:11)
But literally…
In Genesis 15:7 God says to Abraham directly “I am Yahweh” (Genesis 15:7 Hebrew Text Analysis)
In Genesis 15:8 Abraham literally says back “Lord Yahweh” (Genesis 15:8 Hebrew Text Analysis)
Sarah knew Yahweh’s name too (Genesis 16:2, Genesis 16:2 Hebrew Text Analysis)
Genesis 18:4 also has God directly referring to himself as “Yahweh” (Genesis 18:14 Hebrew Text Analysis)
Genesis 22:14 records Abraham calling the place of Isaac’s Sacrifice “Yahweh will provide” (Genesis 22:14 Hebrew Text Analysis)
Jacob in his dream… literally God says I’m Yahweh (Genesis 28:13 Hebrew Text Analysis)
Okay you get the point. So what gives? Am I misunderstanding something here? All over Genesis is the interaction with Abraham, Isaac and Jacob involved with calling God ‘Yahweh’ many times directly.
This is just one example I think of hundreds of such multiple traditions preserved in the Old Testament.
