Shemot 6:3 reads: “And I appeared to Avraham, to Yitzchak, and to Ya'akov, by the name of God Almighty (El Shaddai), but by My name, the Lord (the Tetragrammaton/Shem Hameforash) I was not known to them.” Or at least that is how it is usually translated.
A translation such as this seems to imply/suggests that the one who was previously known by the name of El Shadai will now be known by the name of the Tetragrammaton).
Therefore I wondered if the word 'name' (שם) should not be understood as 'title/description' like a noun?! In Hebrew grammar, the word ‘shem’ means a ‘noun.’ In that case God would be called God in the same way as Adam is called Adam (or should it be understood in the way Shem is called Shem).
