In the Hebrew Scriptures, the word eloh′ah (god) has two plural forms, namely, elo·him′ (gods) and elo·heh′ (gods of). These plural forms generally refer to Jehovah, in which case they are translated in the singular as God. Do these plural forms indicate a Trinity? No, they do not. In A Dictionary of the Bible, William Smith says: The fanciful idea that [elo·him′] referred to the trinity of persons in the Godhead hardly finds now a supporter among scholars. It is either what grammarians call the plural of majesty, or it denotes the fullness of divine strength, the sum of the powers displayed by God.
The American Journal of Semitic Languages and Literatures says of elo·him′: It is almost invariably construed with a singular verbal predicate, and takes a singular adjectival attribute. To illustrate this, the title elo·him′ appears 35 times by itself in the account of creation, and every time the verb describing what God said and did is singular. (Genesis 1:12:4) Thus, that publication concludes: [Elo·him′] must rather be explained as an intensive plural, denoting greatness and majesty.
Elo·him′ means, not persons, but gods. So those who argue that this word implies a Trinity make themselves polytheists, worshipers of more than one God. Why? Because it would mean that there were three gods in the Trinity. But nearly all Trinity supporters reject the view that the Trinity is made up of three separate gods.
The Bible also uses the words elo·him′ and elo·heh′ when referring to a number of false idol gods. (Exodus 12:12; 20:23) But at other times it may refer to just a single false god, as when the Philistines referred to Dagon their god [elo·heh′]. (Judges 16:23, 24) Baal is called a god [elo·him′]. (1 Kings 18:27) In addition, the term is used for humans. (Psalm 82:1, 6) Moses was told that he was to serve as God [elo·him′] to Aaron and to Pharaoh.Exodus 4:16; 7:1.
Obviously, using the titles elo·him′ and elo·heh′ for false gods, and even humans, did not imply that each was a plurality of gods; neither does applying elo·him′ or elo·heh′ to Jehovah mean that he is more than one person, especially when we consider the testimony of the rest of the Bible on this subject.
