Analysis of Easter Song

I Got me flowers to straw Thy way,  
I got me boughs off many a tree;  
But Thou wast up by break of day,  
And brought’st Thy sweets along with Thee.  

The sunne arising in the East,          
Though he give light, and th’ East perfume,  
If they should offer to contest  
With Thy arising, they presume.  

Can there be any day but this,  
Though many sunnes to shine endeavour?         
We count three hundred, but we misse:  
There is but one, and that one ever.
