Shakespeare's Sonnets: Let not my love be call'd idolatry

Let not my love be call'd idolatryNor my belovèd as an idol show,Since all alike my songs and praises beTo one, of one, still such, and ever so.Kind is my love to day, to morrow kind,Still constant in a wond'rous excellence.Therefore my verse to constancy confin'd,One thing expressing, leaves out difference.Fair, kind, and true, is all my argument,Fair, kind and true, varying to other words,And in this change is my invention spent,Three themes in one, which wond'rous scope affords. Fair, kind, and true have often liv'd alone, Which three till now never kept seat in one.
