the sonnets and a lovers complaint

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.’
