When the Armies Surround Jerusalem

The sleeping slumber, slipped     My startled soul 
When the Phalanxes fell     Fated upon the frail faults 
Where they beat perfectly brazen     Beasts on the first battle. 
But, the great horsemen came harrowing    Harrowed upon the hills 
And the Phalanxes could not turn     For, though Cyrus fought in those Phalanxes 
Alexander the Great aligned himself     With the all coming animals 
Who would feast upon flesh     In battles gross and bald. 
Thus, the Phalanxes could not furnish     Their foes, for Alexander's rush attacked 
Them from the port guard, and grueling     Gore spilled over the gargantuan gorges. 
Cyrus' numbers were no more.     Alexander had numbered them with the null. 
Who will assay Alexander though?    The Abomination surrounded Ariel  
And who, but Christ, will Christen the victor won?    Can anyone but He defeat and pay the cost? 
Therefore, Jeshurun, flee to the hillocks and dales     And don't come down, even if he says "I am David".
