"Look like th'innocent flower, but be the serpent under't"
• Passive image "innocent flower" juxtaposes active corruption of "the serpent", reflecting the ideas of "fair" and "foul" in Act 1, Scene 1. Distinction is not a predicament, but becomes a specific strategy to gain political power.
• Relate to biblical allusions - Garden of Eden. Is especially evocative as Lady Macbeth is engaged in supernatural paganism; she is asking her husband symbolically to strike out against Christian ideals - role of biblical villain?
