אֵל שַׁדַּי El Shaddai

[Hanseng]

El Shaddai is usually translated as God Almighty in the KJV. YHVH is usually translated as LORD. Rather than use the sacred name, some Jews use the Hebrew term Ha Shem. Ha Shem means "the name." A Jewish legend describes a creature made of sand who could be brought to life by inscribing  יְהוָה  YHVH  in his forehead. Another version of the story says he was activated by putting a piece of paper with the sacred name in his ear. This being, known as a golem, was said to have helped the Jews during difficult times. The Golem of Prague is the best known.

Exodus 6:3 says that the patriarchs knew God as El Shaddai but not as YHVH.

Why Scripture says this is a puzzle. Several verses in Genesis include the term YHVH in a sense that indicates that the God of Abraham was also known as YHVH, e.g.,  Genesis 16:2, 22:14. Genesis 15:7, God identifies himself to Abraham as YHVH, yet Exodus 6:3 says the patriarchs did not know God by that name. 

Any thoughts?

Although Exodus 6:3 says" And I appeared unto Abraham, unto Isaac, and unto Jacob, by [the name of] God Almighty [El Shaddai], but by my name JEHOVAH was I not known to them."

Genesis 14:22: But Abram said to the king of Sodom, “I have raised my hand to the LORD [YHVH], God Most High, the Possessor of heaven and earth,

 Genesis 27:7    ‘Bring me game and make savory food for me, that I may eat it and bless you in the presence of the LORD [YHVH before my death.’

Genesis 27:20 But Isaac said to his son, “How [is it] that you have found [it] so quickly, my son?” And he [Jacob] said, “Because the LORD [YHVH your God brought [it] to me.” 

 The above 3 verses indicate that Abraham, Issac, and Jacob  all referred to God as YHVH.

Additionally, Abraham's servant took an oath in the name of YHVH and prayed in his name Genesis 24: 7, 12.

Rebekah's brother Laban referred to Abraham's servant as Blessed of the LORD [YHVH] Genesis 24:31.

Her father Bethuel also knew the God YHVH, Genesis 24:50.
