How many Chapter must Israel take?? Before this come to and end?

How many ears must one man have,
Before he can hear people cry?
Yes, 'n' how many deaths will it take till he knows,
That too many people have died?
Yes, 'n' how many times must the cannon balls fly,
Before they're forever banned?
Yes, 'n' how many years can some people exist,
Before they're allowed to be free?
Yes, 'n' how many times can a man turn his head,
Pretending he just doesn't see?

The answer, my friend, is blowin' in the wind,
The answer is blowin' in the wind.
