These verses place the final gathering and salvation of Israel into the historical context of the miraculous salvation of the house of Jacob from Egypt. This future gathering is very explicitly placed into the very same terms and images as the original Exodus. Thus the Lord emphasizes the miraculous power of the future by linking it to the power of the past. The national consciousness of all of the house of Jacob was shaped by the Exodus, and this new kingdom will be a return to that close presence and powerful protection off the Lord, who lead them by day and night. That same Lord who saved his people by opening dry land through the sea will do so again to create a highway to bring his people home.
