Sonnet 145:

Those lips that Love's own hand did make
Breath'd forth the sound that said I hate
To me that languish'd for her sake:
But when she saw my woeful state,
Straight in her heart did mercy come.
Chiding that tongue, that ever sweet
Was used in giving gentle doom:
And taught it thus anew to greet:
'I hate' she alter'd with an end
That follow'd it as gentle day
Doth follow night, who like a fiend
From heaven to hell is flown away.
'I hate' from hate away she threw,
And sav'd my life, saying 'not you'
