There are a few sonnets I considered but these are the ones I like best, each of which seems to me to have two useful phrases.

1. To Whom in Vassalage -or- Whatsoever Star That Guides

Sonnet XXVI

Lord of my love, to whom in vassalage
Thy merit hath my duty strongly knit,
To thee I send this written embassage,
To witness duty, not to show my wit:
Duty so great, which wit so poor as mine
May make seem bare, in wanting words to show it,
But that I hope some good conceit of thine
In thy soul's thought, all naked, will bestow it;
Till whatsoever star that guides my moving
Points on me graciously with fair aspect
And puts apparel on my tatter'd loving,
To show me worthy of thy sweet respect:
Then may I dare to boast how I do love thee;
Till then not show my head where thou mayst prove me.

2. Whose Blessed Key -or- Feasts So Solemn

Sonnet LII

So am I as the rich, whose blessed key
Can bring him to his sweet up-locked treasure,
The which he will not every hour survey,
For blunting the fine point of seldom pleasure.
Therefore are feasts so solemn and so rare,
Since, seldom coming, in the long year set,
Like stones of worth they thinly placed are,
Or captain jewels in the carcanet.
So is the time that keeps you as my chest,
Or as the wardrobe which the robe doth hide,
To make some special instant special blest,
By new unfolding his imprison'd pride.
Blessed are you, whose worthiness gives scope,
Being had, to triumph, being lack'd, to hope.
