Drop down, ye heavens, from above, and let the skies pour down righteousness.
Be not wroth very sore, O Lord, neither remember iniquities for ever: thy holy cities are a wilderness, Sion is a wilderness, Jerusalem a desolation: our holy and our beautiful house, where our fathers praised thee.
Drop down, ye heavens, from above, and let the skies pour down righteousness.
We have sinned, and are as an unclean thing, and we all do fade as a leaf: our iniquities, like the wind' have taken us away; thou hast hid thy face from us: and hast consumed us, because of our iniquities.
Drop down, ye heavens, from above, and let the skies pour down righteousness.
Ye are my witness, saith the Lord, and my servant whom I have chosen; that you 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.
Drop down, ye heavens, from above, and let the skies pour down righteousness.
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.
Drop down, ye heavens, from above, and let the skies pour down righteousness.
