Help for equivocation in macbeth

hey everyone
im doing an essay on macbeth and i need some help.
My topic is "Situations in which characters equivocate"
which in other words means situations in which charcters purposly use language that can be understood in more than one way, in order to avoid the truth.

i have a couple points for my essay but i need a few more. If anyone has any points, advice or knowledge on the use of equivocation in macbeth could you please help me out? it would be greatly appreciated.
thank you in advance.

The witches are the primary equivocators in the play. The best examples of this occurs in Act 4 scene 1. Much of the play deals with how language can be misused to say one thing and mean another.

Faith here's an Equiuocator, that could sweare in both
the Scales against eyther Scale, who committed Treason
enough for Gods sake, yet could not equiuocate to Heauen:
oh come in, Equiuocator.

much Drinke may be said to be an Equiuocator with Lecherie:
act 2 scene 3
