Kabbalah sa Ezekiel 38:23: Sha'arei Orah

Now, you might say, “If we were redeemed from Egypt with this quality, why then was the Shofar not sounded then?” The explanation is that during that exile, we were only under the dominion of Egypt. However, in this exile, in which we are under the dominion of all the supernal ministering angels and all of the families of the earth, it is necessary to awaken His great power over them, with thundering, great commotion, and the sound of the Shofar, as it states,²⁴¹Ezekiel 38:23 “I will be exalted, and I will be sanctified, and I will make Myself known before the eyes of many nations.”
