תּלמוד אויף בראשית 31:53

In the verse “For YHVH (tetragrammaton) your God is HAELOHEI HAELOHIM (God of gods)” (Deuteronomy 10:17) the first name (HAELOHEI) is holy and cannot be erased while the second (HAELOHIM) is non-holy and can be erased. The verse continues “and ADONAI HAADONIM (Lord of lords)” the first name is holy and the second name is non-holy. In the verse “God of Abraham” (Genesis 31:53) the word “God” is holy; “god of Nachor” is non-holy. “Their ancestral gods” is non-holy. In the verse “You shall not curse ELOHIM” (Exodus 22:27) ELOHIM has both holy and non-holy interpretations. Rabbi Yishmael says it’s holy.

"And Lord of lords" (ibid.) - the first 'Lord' is holy, the second isn't. "God of Abraham" (Genesis 31:53) is holy, "God of Naḥor" (ibid.) isn't. "God do not curse" (Exodus 22:27) could be holy or not - Rabbi Shimon says, holy. "For seeing your face is like seeing the face of God" (Genesis 33:10) - this is definitely not holy. "Camp of God" (Genesis 32:2) - this is definitely holy.
