"I will open a way, not merely in the Red Sea, but in the wilderness of the whole world; and not merely one river shall gush out of the rock, but many, which shall refresh, not the bodies as formerly, but the souls of the thirsty, so that the prophecy shall be fulfilled: 'With joy shall ye draw water out of the wells of salvation'" [JEROME]. "A way" often stands for the true religion (Ac 9:2; 18:26). "Rivers" express the influences of the Holy Spirit (Joh 7:37-39). Israel's literal restoration hereafter is included, as appears by comparing Isa 11:15, 16.
