This article examines the meaning of the phrase “sons of God” in Genesis 6:1–4, presenting three major interpretations. The first identifies them as the godly line of Seth intermarrying with the ungodly line of Cain. The second sees them as demon-possessed men. The third—and most strongly supported—view holds that the “sons of God” were fallen angels who took on human form and cohabited with women, producing a hybrid offspring. This view is reinforced by consistent usage of the Hebrew phrase bene ha-Elohim in reference to angels, supporting biblical texts (Job, 1 Pet 3:19-20; 2 Pet 2:4; Jude 6–7), and longstanding Jewish and early Christian interpretation.
