Ha, Bartlett's, I should'a known!!! Many thanks.
I suppose this is the original from which Page drew; obviously, "please" refers to one "pleased" to perform the Almighty's orders, that is here an angel. Though where Addison drew inspiration for an angel that "rides in the whirlwind and directs the storm" is still a good question.
The phrase is eloquent, but as noted in the material you posted, it seemed incongruous in the Inaugural. It eloquently implies judgment or chastisement.
