"El"... notice that God said that He was known by the name "El' before giving His name as "YHVH". Most of the time in the Bible Êl is translate as God in the singular form and Elohim in its plural form.Ex.6:2-3 I revealed myself to Abraham, to Isaac, and to Jacob as Êl of the Wilderness but was not known to them by My Name YHVH
Êl-Shaddai
Êl-Elyon
So.... is it true that the name YHVH was not known to Abraham, Issac and Jacob?
