And now thow woldest falsly been aboute
To love my lady, whom I love and serve,
And evere shal til that myn herte sterve.
And ever shall until my heart dies.
Nay, certes, false Arcite, thow shalt nat so.
I loved hire first, and tolde thee my wo
As to my conseil and my brother sworn.

– Geoffrey Chaucer

The Canterbury Tales, The Knight’s Tale. Palamon tells Arcite that he has first claim on Emily, simply because he loved her first and told his sworn brother and confidant Arcite "my wo." He accuses Arcite of falsely preparing to love his lady, whom he is pledged to love and serve until his heart dies. He warns Arcite that he will not do so, foreshadowing the bloody feud that later happens between the two.
