If Old Testament Judaism was a monotheistic religion, and Yahweh wanted to distinguish the Hebrews from their neighboring countries' polytheistic religions, why is His name אֱלוֹהִים (Elohim) plural?
אֱלוֹהִים (Elohim) is used "no less than 2,500 times" (Pohle-Preuss vol. 1 Part II, ch. 1, §1, §§1).
My question is more general than "In Genesis 20:13, why is elohim with a plural verb translated God rather than gods?" or "Why is Elohim translated as God rather than gods in Genesis 1:1?."
