אֱלֹהֵינוּ= “Elohim”
“Elohim” definition:
H430 A masculine plural noun. God, gods, judges, angels. This is not a “Plural of Majesty”. A better reason can be seen in scripture itself where, in the very first chapter of Genesis, the necessity of a term conveying both the unity of the one God and yet allowing for a plurality of persons is found (Gen 1.2, 26). This is further borne out by the fact that the form “Elohim” occurs only in Hebrew and in no other Semitic language, not even in Biblical Aramaic. Plural of H433; gods in the ordinary sense; but specifically used (in the plural thus, especially with the article) of the supreme God; occasionally applied by way of deference to magistrates; and sometimes as a superlative: - angels, X exceeding, God (gods) (-dess, -ly), X (very) great, judges, X mighty.
H433 “eloah” Masculine singular noun. God or god. From H410; a deity or the deity: - God, god. See H430.
