Alas! 'tis true, I have gone here and there,
And made my self a motley to the view,
Gor'd mine own thoughts, sold cheap what is most dear,
Made old offences of affections new;
Most true it is, that I have look'd on truth
Askance and strangely; but, by all above,
These blenches gave my heart another youth,
And worse essays prov'd thee my best of love.
Now all is done, save what shall have no end:
Mine appetite I never more will grind
On newer proof, to try an older friend,
A god in love, to whom I am confin'd.
  Then give me welcome, next my heaven the best,
  Even to thy pure and most most loving breast.
