The battle through time

I pass to you my sword
I pray that you keep it safe
Rested upon your shoulders
Now a heavy burden lies
Take my cloak to protect you
As I no longer can
But know that you are ready
Like no other man
I've passed to you my wisdom
In all that I have done
To battle until the end of time
A battle that can't be won
There will come a day
When the sword is no longer yours
Pass it to the next man
To open up new doors
