Translation of the Kinah דממו שרפים (found on page 290 of the Or VaDerech siddur for fast days). The Hebrew text and recordings are available at http://www.piyut.org.il/textual/741.html
The seraphim stopped their song, and the chayot and ofanim stopped their watch on the day the decree was finalized and sealed the angels of peace began weeping bitter tears
And the stars darkened at their leaving and the host of the heavens donned sackcloth and the chayot wailed and cried with the ofanim opposite them
The day the strangers' hand grew strong in the mikdash and you burned a fire in the inner sanctuary two wings of the chayot were removed and in the straits I converge dirges.
(My beloved, when will you return to the refuge (of the beit Hamikdash) and return the hearts of fathers to their children? When will the faithful praise and revere you, and the chayot and ofanim sanctify you?
The serafim in words and the ofanim with song the angels of peace cry bitterly and scream with an embittered heart and call to each other and say [Kedushah].)
