אור גדול במחצית השמים

An anonymous thirteenth-century biblical commentary, entitled Doresh Reshumot, exhibits an unusual cosmogony. One important feature of this cosmogony is that the sun was "hung" at the meridian of Jerusalem on the fourth day of creation, thus ensuring that its most potent light – and concomitant spiritual power – shines upon the holy city. Elements of this theory may be traced back to 4Q320 (Calendrical Document A), which speaks of the sun's being at the meridian on the fourth day, and to 4Q392's (Works of God) אורתם, that is, 'perfect' or 'full-strength light'.
