Shakespeare's Sonnets: My tongue-tied muse in manners holds her still

My tongue-tied muse in manners holds her stillWhile comments of your praise, richly compil'd,Reserve their character with golden quillAnd precious phrase by all the muses fil'd.I think good thoughts, whil'st other write good words,And like unlettered clerk still cry "Amen"To every hymn that able spirit affordsIn polish't form of well-refinèd pen.Hearing you prais'd, I say, "'tis so, 'tis true,"And to the most of praise add some-thing more,But that is in my thought, whose love to you(Though words come hind-most) holds his rank before. Then others for the breath of words respect, Me for my dumb thoughts, speaking in effect.
