To have a giant’s strength

I came across this passage at the very end of Hawaii’s Story by Lili╩╗uolkalani (scanned copy on Google Books). It’s from Shakespeare’s Measure for Measure, Act 2, Scene 2:

ISABELLA

So you must be the first that gives this sentence,
And he, that suffer’s. O, it is excellent
To have a giant’s strength; but it is tyrannous
To use it like a giant.

[…]
Could great men thunder
As Jove himself does, Jove would ne’er be quiet,
For every pelting, petty officer
Would use his heaven for thunder;
Nothing but thunder! Merciful Heaven,
Thou rather with thy sharp and sulphurous bolt
Split’st the unwedgeable and gnarled oak
Than the soft myrtle: but man, proud man,
Drest in a little brief authority,
Most ignorant of what he’s most assured,
His glassy essence, like an angry ape,
Plays such fantastic tricks before high heaven
As make the angels weep; who, with our spleens,
Would all themselves laugh mortal.
