...O those who pass between fleeting words
It is time for you to be gone
Live wherever you like, but do not live among us
It is time for you to be gone
Die wherever you like, but do not die among us
For we have work to do in our land
We have the past here
We have the first
cry of life
We have the present, the present and the future
We have this world here, and the hereafter
So leave our country
Our land, our sea
Our wheat, our salt, our wounds
Everything, and leave
The memories of memory
O those who pass between fleeting words!

How does the passage above express Palestinian nationalism?
