Rodzaju 31:53 Komentarz: Rashi, Sforno, Radak & Tur HaArokh

אלהי אברהם GOD OF ABRAHAM — Here the word אלהים is holy (i.e. it is the Divine Name). (Genesis Rabbah 74:17)

אלוהי אביהם, Lavan meant that Yaakov could not take offence at Lavan pairing Nachor’s god and Yaakov’s G’d in a single expression. He had chosen Nachor to underline that Nachor’s god was also the god of Terach, who was the father of both Avraham and Nachor.

אלוקי אברהם ואלהי נחור, the first word “elo-hey” is sacred, the second is profane and may therefore be erased, seeing that Nachor had been an idolater. Lavan himself also believed in the gods of his grandfather Nachor. Neither Yitzchok nor Betuel have been mentioned here, seeing they were well known, famous even.
