In the Hebrew Bible there are four words translated "God": El, Elah, Elo'ah, Elohim.
The oldest Semitic word meaning "God" is El. Linguists believe its base meaning is strength or power. "El" is the Strong One, or the Deity (God). The Canaanites called their chief deity El, the Mighty Bull. After the Israelites entered Canaan, they adopted this generic word "El" for their God, though "Elohim" took precedence. In some Canaanite myths, one of El's sons was the notorious Ba'al, the nemesis of the true God throughout much of Israel's history.
In the Bible, El is often combined in proper names: Isra-El; Shmu-El (Samuel); El-ijah; Immanu-El; Jo-El; Dani-El; Beth-El. It's also found in compounds: El Shaddai, El Elyon, El Roi, El Olam.
Elah is the Aramaic word for "God" used in the Aramaic portions of Daniel and Ezra and one verse in Jeremiah (10:11). Its plural form Elahin is used at least once for the true God (Dan 5:23).
Most English Bibles do not distinguish between the four words for "God." But Joseph Rotherham's Emphasized Bible (1902) used different font faces for each.
The word Elo'ah is used some 57 times, mostly in the book of Job. It is likely the singular form behind Elohim.
The generic term for "G/god" Elohim refers to the true "God" (2507x), "gods," "goddesses," and things divine or mighty. It occurs a total of 2600 times in the HB.
The Hebrew name of God is EL. The word derives from a root word meaning "might, strength, power" and probabl derives fomr the Ugaritic term for God.
El is almost always qualified by additional words that further define the meaning that distinguish Him from false gods.
