Those lips that Love's own hand did make
Breathed forth the sound that said 'I hate'
To me that languished 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 altered with an end
That followed 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 saved my life, saying 'not you'
It’s possible, as  Andrew Gurr  asserts, that “hate away” was a  homophonic   pun for “Hathaway” in Early Modern English pronunciation. This would make the woman of this particular sonnet Anne Hathaway, Shakespeare’s wife. 
 
 This, however, is disputed by other commentators, who believe it doesn’t fit with the pattern of the rest of the sonnets.
