For centuries it has been common to chant or sing the text called Rorate Caeli, or the Advent Prose. during Masses and other services at Advent. The complete text is assembled with passages from different chapters by the prophet Isaiah.
Here is an English translation:
Drop down, ye heavens, from above,
and let the skies pour down righteousness.
Be not wroth very sore, O Lord,
neither remember iniquity for ever:
the holy cities are a wilderness,
Sion is a wilderness,
Jerusalem a desolation:
our holy and our beautiful house,
where our fathers praised thee.
We have sinned, and are as an unclean thing,
and we all do fade as a leaf:
and our iniquities, like the wind, have taken us away;
thou hast hid thy face from us:
and hast consumed us, because of our iniquities.
Ye are my witnesses, saith the Lord,
and my servant whom I have chosen;
that ye may know me and believe me:
I, even I, am the Lord, and beside me there is no Saviour:
and there is none that can deliver out of my hand.
Comfort ye, comfort ye, my people,
my salvation shall not tarry:
I have blotted out as a thick cloud thy transgressions:
Fear not, for I will save thee:
for I am the Lord thy God,
the Holy One of Israel, thy Redeemer.
