תּלמוד אויף בראשית 18:3

All seemingly divine names in the Torah that are stated in conjunction with Abraham are holy except the first one (Genesis 18:3). Rabbi Yehoshua says that too is holy.

All the names that are said regarding Abraham are holy except for one that is not - as it is written (Genesis 18:3) "And he said, my lords, if I have found favor in your eyes," but some say that one is holy too. (Genesis 20:13) "And it was, when they made me wander - God אלהים" Rabbi Ḥanina the brother of Rabbi Yehoshua says, "Holy, because if it weren't for God I have been made to wander anyway."
