12إِنّي أَنا رَبُّكَ فَاخلَع نَعلَيكَ ۖ إِنَّكَ بِالوادِ المُقَدَّسِ طُوًىMuhammad AsadVerily, I am thy Sustainer! Take off, then, thy sandals! Behold, thou art in the twice-hallowed valley,1Whereas some commentators assume that the word tuwan (or tuwa) is the name of the "hallowed valley", Zamakhshari explains it, more convincingly, as meaning "twice" (from tuwan or Owan, "twice done") - i.e., "twice-hallowed" - apparently because God's voice was heard in it and because Moses was raised there to prophethood.
