who is the “shem jechezkel”? I never heard of this theory,including the fact that Dovid Hamelech was there. I don’t think this ma’amar makes any sense.
There is a more concrete connection between Dovid hamelech and Adam Horishon in that Dovid was supposed to be born and die right away ,so Adam gave seventy of his years to Dovid and therefore only lived to 930 years and Dovid lived seventy years.
