But that to your sufficiency you join
A will to serve us, as your worth is able.

He has by this bold conjecture undoubtedly obtained a meaning, but,
perhaps not, even in his own opinion, the meaning of Shakespeare.

That the passage is more or less corrupt, I believe every reader
will agree with the Editors. I am not convinced that a line is
lost, as Mr. Theobald conjectures, nor that the change of "but" to
"put", which Dr. Warburton has admitted after some other Editor,
will amend the fault. There was probably some original obscurity
in the expression, which gave occasion to mistake in repetition or
transcription. I therefore suspect that the Authour wrote thus,

--Then no more remains,
But that to your sufficiencies your worth is abled,
And let them work.

THEN NOTHING REMAINS MORE THAN TO TELL YOU THAT YOUR VIRTUE IS
NOW INVESTED WITH POWER EQUAL TO YOUR KNOWLEDGE AND WISDOM. LET
THEREFORE YOUR KNOWLEDGE AND YOUR VIRTUE NOW WORK TOGETHER. It may
easily be conceived how "sufficiencies" was, by an inarticulate
speaker, or inattentive hearer, confounded with "sufficiency as",
and how "abled", a word very unusual, was changed into "able". For
"abled", however, an authority is not wanting. Lear uses it in the
same sense, or nearly the same, with the Duke. As for "sufficiencies",
D. Hamilton, in his dying speech, prays that "Charles II. may exceed
both the VIRTUES and SUFFICIENCIES of his father."
