In the future redemption, a great abundance will flow to enlighten the eyes to understand Torah and bring out the holy sparks from being bound up. It is those souls that have been locked away in their shells.
There are places of ill repute such as houses of idol worship and even those places receive life from God, even though God's glory is far from there. This is what Isaiah meant, "my glory will not be given to others." With all of this, they receive life from the sealed utterance which is Bereishit, which is the highest level of God's glory that is sealed and hidden. From there, they receive this life-force such that when they fall to this place and seek out God's glory, this is their repentance and fixing. Because it returns to the high glory and at that point, they receive the life-force from the great hidden place.
The nations at the the farthest reaches of the world will praise God and will know of the redemption of Israel. Since they are scattered among them, the non-Jews will see the wonders and song God's praises. In land and in sea this will happen. The fish of the sea will do so and this is a parable, similar to the trees of the field clapping.
ה' כגבור יצא, הגבור כחו במתניו ויוצא למלחמה בעצמו, וז"ש כגבור יצא והאיש מלחמות אינו גבור רק מלומד בתכסיסי מלחמה ואיש מלחמות הוא אם בחן מלחמות רבות ובקי בהנהגת המלחמה, והוא אינו לוחם בעצמו רק יעיר קנאה שיודע תחבולות לזרז אנשי החיל ולהעיר קנאה בלבם.
A warrior's strength is in his own abilities to go out to war on his own. He's learned in the art of war. He's a person of war if he chooses to delve into it and is an expert in the behaviors of war. He himself won't fight but rather will arouse vengefulness as he's aware of how to incite his soldiers and awaken vengefulness within them.
Israel, who are miserable in exile, I will lead them by a way they don't know to their land through the desert of the nations.
For a person who walks in the dark or in a roadblocked path will fail. A person who walks a path they don't know, it's as if they're walking in darkness. Israel will walk in light and in security.
