Question: In Exodus 6:2-3 Yahuah states that he appeared to Abraham, Isaac and Jacob by El-Shaddai but His name Yahuah was not known to them. But as we can see in Genesis in many occurances that Abraham was using and saying the name of Yah in many of his questions to conversating with Him, for example: Genesis 15 or 18:27-32 and many more instances. Did they really called upon the name of Yahuah or is it a way that Mosheh used and has written Genesis in order for the Name of Yahuah be clear throught out all the Torah? I believe is the second because by no means our Creator Yahuah Almighty is a liar, i just need some answers and opinions by the family. Thanks. Much love. All praises to the Magnificent and Awsome name of Yahuah through our King and Messiah Yahusha. Shalom.
