YHWH makes a covenant with Abram and first changes his name to Abraham, but how does this relate to the covenant? I’m interested because YHWH’s name is mentioned about 7,000 times in the tanach so there must be a significance to the importance of his name being changed. I'm not asking why there is a name change or what the relevance of the name is to YHWH.
What I’m not understanding is how the name change relates to the covenant.
“And God said to him, “Behold, my covenant is with you, and you shall be the father of a multitude of nations. No longer shall your name be called Abram, but your name shall be Abraham, for I have made you the father of a multitude of nations. I will make you exceedingly fruitful, and I will make you into nations, and kings shall come from you. And I will establish my covenant between me and you and your offspring after you throughout their generations for an everlasting covenant, to be God to you and to your offspring after you. And I will give to you and to your offspring after you the land of your sojournings, all the land of Canaan, for an everlasting possession, and I will be their God.” (Genesis 17:4-8, KJV)
The passage continues on about circumcision and Sarai's name is changed to Sarah. Interesting to me is the "ha" added to him and the "ah" added to her. Is this connected to the covenant -it seems so. No vowels in Hebrew so YHWH is adding the same letter prevalent in YHWH's name -the "hey." The "hey" is breath.
How does this relate to the covenant?
