He is basically saying to get the real story before you turn them into a lie. Basically stating that you need to know the entire story before you make it into some fairytail of lies. When someone has the facts with concrete evidence you cannot twist it into a lie, thus it is stubborn; But statistics are easily twisted because they do not have the evidence to back them up, because they are simply statistics, not facts. Idk if this works but hope it helps!
I am not too sure if these are the only such lines, but here is one deifinitely good answer:
'My will to her consent is but a part.
An she agreed within her scope of choice"
They are from Scene 2.
Those words mean that Capulet's daughter is free to choose her husband, at least in part (with the father's agreement)
Macbeth is easy to manipulate and Banquo isn't as easy to fool. Banquo can sense something isn't right (like Macbeth is being tricked) :)
Line 4: “Keel” has multiple meanings. The first is the part of the ship that goes along the underside that gives the ship stability in the water. This usage really doesn’t make much sense, though, because one can’t see a “steady keel” unless the boat has fallen over. The other use of keel here is as a synecdoche. The keel, a part of a boat, is used to represent the whole boat. More importantly, "the steady keel" lets us know that, despite its rough trip, the ship (like the nation) remains steadfast and true.
