The Lord will march out like a champion,
    like a warrior he will stir up his zeal;
with a shout he will raise the battle cry
    and will triumph over his enemies.

The Lord is about to do a new thing. As He once led His people out of Egypt and through the wilderness, so there is going to be a second ‘exodus’, with Him at the Head. But although, in the short-term, the new thing is about the return of Israel from Babylon, as we saw yesterday this prophecy also has the long-term in view. It foresees the coming of Jesus, His building of an international church, and here in this verse, His conquest at the Cross. As I read verses 13, a couple of New Testament passages coming into mind:

”And having disarmed the powers and authorities, he made a public spectacle of them, triumphing over them by the cross.” Col.2:15;

 ”Since the children have flesh and blood, he too shared in their humanity so that by his death he might break the power of him who holds the power of death—that is, the devil— 15 and free those who all their lives were held in slavery by their fear of death.” Hebrews 2:14,15.
