The stars cleave the sky. 
Yet for us they rest, 
And their race-course high 
Is a shining nest! 
 
The hours hurry on. 
But where is thy flight, 
Soft pavilion 
Of motionless night? 
 
Earth gives up her trees 
To the holy air; 
They live in the breeze; 
They are saints at prayer! 
 
Summer night, come from God, 
On your beauty, I see, 
A still wave has flowed 
Of eternity!
George MacDonald
