1. Creation and the Fall: Similar to the account in the Book of Genesis, _Beowulf_ opens with the creation of the world and the subsequent rebellion of the monster Grendel against the order established by God. There are also references to the descent of Grendel into darkness, which can be seen as a parallel to the fall of Lucifer.
2. Cain and Abel: The theme of fratricide, particularly in the context of Hrothgar's feud with his brother, King Onela, reflects the biblical story of Cain and Abel, where Cain kills his brother out of jealousy.
3. The Flood: The description of the flood that devastated the world in _Beowulf_ draws parallels to the biblical account of Noah's Ark. The flood serves as a punishment for the sins of humanity and is depicted as a catastrophic event that destroyed all life, except for a chosen few who found salvation.
4. Babylonian Captivity: The depiction of Beowulf's rescue of Hrothgar's people from the clutches of the monster Grendel can be seen as a reference to the deliverance of the Israelites from the Babylonian captivity. Grendel's cave symbolizes the oppressive rule of the Babylonians, and Beowulf's victory represents liberation and salvation from this oppressive force.
5. The Crossing of the Red Sea: The description of Beowulf's underwater battle with Grendel's mother resembles the biblical account of Moses leading the Israelites across the Red Sea. Both involve a perilous journey through water and a divine intervention that ensures victory against a powerful enemy.
These biblical references indicate the influence of Christian beliefs on the Anglo-Saxon society during the time when _Beowulf_ was composed, and they shed light on the ways in which the poem resonates with universal themes and motifs found in religious literature.
