Avraham seems to mean a father of a multitude or exalted father. But is there any scripture that calls him Av Ha'am? A father of nations or our nation?
I read an article which wrote that Avraham was a Av Ha'am, but I wonder if this terminology of Av Ha'am was mentioned anywhere in the Talmud or other scriptures? Because the Torah calls him a father of a multitude of nations (goyim) and not amim or just am.
