Isaiah 35:6-8
6. leap—literally, "fulfilled" (Ac 3:8; 14:10).
sing—joyful thanksgiving. in . . . wilderness . . . waters— (Isa 41:18).7. parched ground—rather, "the mirage (Hebrew, Sharab, 'the sun's heat') shall become a (real) lake." The sun's rays refracted on the glowing sands at midday give the appearance of a lake of water and often deceive the thirsty traveller (compare Jer 2:13; Isa 41:18).
dragons—rather, "jackals." each—namely, jackal. grass—rather, "a dwelling or receptacle (answering to the previous habitation) for reeds," &c. (which only grow where there is water, Job 8:11). Where once there was no water, water shall abound.8. highway—such a causeway (raised way, from a Hebrew root, "to cast up") as was used for the march of armies; valleys being filled up, hills and other obstructions removed (Isa 62:10; compare Isa 40:3, 4).
way of holiness—Hebraism for "the holy way." HORSLEY translates, "the way of the Holy One;" but the words that follow, and Isa 35:10, show it is the way leading the redeemed back to Jerusalem, both the literal and the heavenly (Isa 52:1; Joe 3:17; Re 21:27); still Christ at His coming again shall be the Leader on the way, for which reason it is called, "The way of the Lord" (Isa 40:3; Mal 3:1). it shall be for those: the wayfaring men—rather, "He (the Holy One) shall be with them, walking in the way" [HORSLEY]. though fools—rather, "And (even) fools," that is, the simple shall not go astray, namely, because "He shall be with them" (Mt 11:25; 1Co 1:26-28).Isaiah 43:19
19. new—unprecedented in its wonderful character (Isa 42:9).
spring forth—as a germinating herb: a beautiful image of the silent but certain gradual growth of events in God's providence (Mr 4:26-28). way in . . . wilderness—just as Israel in the wilderness, between the Red Sea and Canaan, was guided, and supplied with water by Jehovah; but the "new" deliverance shall be attended with manifestations of God's power and love, eclipsing the old (compare Isa 41:17-19). "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.Isaiah 49:10-11
10. Messiah will abundantly satisfy all the wants, both of literal Israel on their way to Palestine, and of the spiritual on their way to heaven, as their Shepherd (Isa 65:13; Mt 5:6), also in heaven (Re 7:16, 17).
11. my—All things are God's.
mountains a way—I will remove all obstructions out of the way (Isa 40:4). exalted—that is, cast up (Isa 57:14; 62:10); for instance, over valleys. VITRINGA explains "mountains" as great kingdoms, Egypt, Syria, &c., subjected to Rome, to facilitate the spreading of the Gospel; "highways," the Christian doctrine wherein those who join the Church walk, and which, at the time of Constantine, was to be raised into prominence before all, and publicly protected (Isa 35:8, 9).
