In the New Testament, the term "godhead" does not appear in most translations. However, in the King James Version (KJV), it does appear in Colossians 2:9 and Acts 17:29:
In Colossians 2:9: “For in him [Christ] dwelleth all the fulness of the Godhead bodily."
In this verse, "godhead" is translated from the Greek word "θεότης" (theotēs), which refers to the divine nature or deity.
In the Greek text of Acts 17:29, the word translated as "godhead" in the King James Version is "θεῖον" (theion), which can also be translated as "divine nature" or "divinity."
In Greek philosophical and religious thought, the terms "theotēs" (θεότης) and "theion" (θεῖον) generally conveyed a sense of divinity or godliness without necessarily implying a singular deity. These terms were used to describe divine qualities, attributes, or manifestations, which could be applied to various gods or divine beings within the Greek pantheon.
In Hebrew, the closest equivalent to the Greek concept of "theion" (θεῖον) or "theotēs" (θεότης) would be the term "אֱלֹהִים" (Elohim), which is often translated as "God" or "gods" in English.
