Analysis of Sing a New Song

O sing a new song, to our God above,
Avoid profane ones, 'tis for holy choir:
Let Israel sing song of holy love
To him that made them, with their hearts on fire:
Let Zion's sons life up their voice, and sing
Carols and anthems to their heavenly king.

Let not your voice alone his praise forth tell,
But move withal, and praise him in the dance;
Cymbals and harps, let them be tuned well,
'Tis he that doth the poor's estate advance:
Do this not only on the solemn days,
But on your secret beds you spirits raise.

O let the saints bear in their mouth his praise,
And a two-edged sword drawn in their hand,
Therewith for to revenge the former days,
Upon all nations, that their zeal withstand;
To bind their kings in chains of iron strong,
And manacle their nobles for their wrong.

Expect the time, for 'tis decreed in heaven,
Such honor shall unto his saints be given.
