quotes on feud is the reason that romeo and juliet died

From forth the fatal loins of these two foes
A pair of star-crossed lovers take their life;
Whole misadventured piteous overthrows
Do with their death bury their parents' strife.
The fearful passage of their death-marked love,
And the continuance of their parents' rage,
Which, but their children's end, naught could remove,
Is now the two hours' traffic of our stage;
The which, if you with patient ears attend,
What here shall miss, our toil shall strive to mend. (Chorus/ Prologue)

O Romeo, Romeo, wherefore art thou Romeo?
Deny thy father and refuse thy name,
Or, if thou wilt not, be but sworn my love,
And I'll no longer be a Capulet. (Juliet/ Act II/ Scene II)

How camest thou hither, tell me, and wherefore?
The orchard walls are high and hard to climb,
And the place death, considering who thou art,
If any of my kinsmen find thee here. (Juliet/ Act II/ Scene II)
