All this is as nothing compared to the voice of Judah, which
made all Egypt quake and tremble, and Pharaoh fall from his
throne headlong, etc., etc. See Jasher, chap. 64, verses 46, 47.
The distance from the earth to the firmament is five hundred years'
journey, and so it is from each successive firmament to the next,
throughout the series of the seven heavens.
THE TALMUD, _P'sachim_, fol. 94, col. 2.
