Eternal return cycle

Ouroboros

The circular nature of the Ouroboros symbolizes the cyclical essence of existence, where endings seamlessly flow into new beginnings, and death gives way to rebirth.

Apep

Crucially, in most tellings Apep is never permanently destroyed, only cut down, repelled, or driven off night after night, only to reconstitute himself and renew the assault the following night; this endless cycle made Apep less a monster to be defeated once and for all than a permanent cosmic principle, the personification of isfet (chaos, non-being, disorder) standing in eternal opposition to maat (truth, order, cosmic balance) that Ra and the pharaoh alike were charged with upholding.

Baal

In his home tradition Baal's central story is a contest for kingship among the gods, fought first against Yam, god of sea and the primeval waters, whom he defeats and so establishes his rule, and then against Mot, god of death, who overpowers him — an episode comparative mythographers read as tied to the withholding and return of seasonal rain.
