Three angels came tonight
To bring me very beautiful things
One of them had a censer
Another had a bouquet of roses
And the third had in hand
A very flowery robe
Of pearls, gold and jasmine
Like Madame Marie has.

Hallelujah, Hallelujah, we come from heaven
To bring you what you desire
Since the good God at the top of the sky
Is sad when you sigh.

Do you want the beautiful golden censer
Or the ring of blossoming roses?
Do you want the dress or perhaps
A necklace with silver flowers?
Do you want some heavenly fruits
Or wheat from celestial barns?
Or like long-ago shepherds
Do you want to see Jesus in his swaddling clothes?

Hallelujah, Hallelujah, return to heaven
My beautiful angels, at this very instant;
In the blue sky ask God
For happiness for the one I love.
