Final answer:
The play Macbeth references the biblical allusions of Adam and Eve and Cain and Abel through thematic similarities, such as Macbeth's moral downfall and the fratricidal elements akin to Cain and Abel.
Step-by-step explanation:
The biblical allusions referenced by the play Macbeth include both Adam and Eve and Cain and Abel. While the play does not directly mention these biblical stories, it contains thematic elements that allude to them. The struggle between Macbeth and Banquo, for instance, can be seen as reflecting the Cain and Abel motif of jealousy and fratricide. Macbeth's fall from grace and the loss of his moral compass can be compared to the story of Adam and Eve and their expulsion from the Garden of Eden after giving in to temptation.
