(Exodus 19:19) "And the voice of the shofar": This is a propitious sign in Scripture. Wherever "shofar" is mentioned, this is propitious for Israel, viz. (Psalms 47:6) "G–d has risen with teruah (the shofar blast); the L–rd, with the sound of the shofar", (Isaiah 27:13) "And it shall be on that day, it shall be sounded by a great shofar, etc.", and (Zechariah 9:14) "And the L–rd G–d will blow the shofar, and will go in a tempest against Teiman (Edom)."
