Lady Macbeth
All our service,
In every point twice done and then done double,
Were poor and single business to contend
Against those honors deep and broad wherewith
Your Majesty loads our house.
1.6.18-22
Here, Lady Macbeth is lying through her teeth while still managing to profoundly impress Duncan. She’s basically saying that in preparation for Duncan, her and her servants prepared every aspect of this dinner four times over - but that was nothing in comparison to the deep honors which Duncan brings them by visiting. Her quote can be seen as having a double meaning, since we know that she’s planning something evil - if it’s as much as murder (which we’ll find out it is), then indeed, she’s getting the biggest honors due to Duncan’s arrival.
