Isaiah 57:14

“And shall say, cast ye up, cast ye up, &c.] A causeway, a highway, for the people of the Jews to return to their own land: this is either said by the Lord, as some supply it; or by the prophet, as Jarchi; or by him that putteth his trust in the Lord, as Kimchi; or rather by one, that is, the first of the living creatures, a set of Gospel ministers, that shall give to the angels, the Protestant princes and potentates, the seven last vials to pour out on the antichristian states, both Papal and Mahometan, and shall stir them up to do it; or the voice out of the temple, that shall order them to do their work; by which means way will be made for the return of the said people, (<661507>Revelation…”

“shall say--The nominative is, "He that trusteth in Me" (Isa 57:13). The believing remnant shall have every obstacle to their return cleared out of the way, at the coming restoration of Israel, the antitype to the return from Babylon (Isa 35:8; Isa 40:3-4; Isa 62:10-11). Cast . . . up--a high road before the returning Jews. stumbling-block--Jesus had been so to the Jews, but will not be so then any longer (Co1 1:23); their prejudices shall then be taken out of the way.”

“And shall say - Lowth, ‘Then will I say.’ Noyes, ‘Men will say.’ The word אמר 'âmar seems to be used here impersonally, and to mean, ‘One shall say;’ that is it shall be said. The Septuagint and the Syriac render it, ‘They shall say.’ The idea is, that the obstacles would be removed from the path of those who put their trust in God. The language is derived from the return from the exile, as if persons should go before them and should cry, ‘Cast ye up;’ or as if the cry of the people all along their journey should be, ‘Remove the obstacles to their return.’ Cast ye up, cast ye up - That is, remove the obstacles; level the hills; take up any obstruction out of the way (compare the notes at…”

“And he - God will raise up a man who shall say with authority and efficacy. Cast up - Make causeways, where it is needful, for their safe and easy passage, and remove all things which may hinder them in their return. Isaiah 57:16”

“57:14-21 The Lord here promises to be present with the humble, to heal them, and to grant them his peace. The promise extends to all the citizens of Zion, both Jews and Gentiles. The Holy One comes to the humble with an all-inclusive offer of salvation, while dealing justly with the wicked.”

“Cast: Isa 35:8, Isa 40:3, Isa 62:10; Luk 3:5, Luk 3:6 take: Rom 14:13; Co1 1:23, Co1 8:9, Co1 8:13, Co1 10:32, Co1 10:33; Co2 6:3; Heb 12:13 Isaiah 57:15”

“The promise is now followed by a appeal to make ready the way which the redeemed people have to take. "And He saith, Heap up, heap up, prepare a way, take away every obstruction from the way of my people." This is the very same appeal which occurs once in all three books of these prophecies ( Isa 40:3-4; Isa 57:14; Isa 62:10). The subject of the verb ('âmar) is not Jehovah; but the prophet intentionally leaves it obscure, as in Isa 40:3, Isa 40:6 (cf., Isa 26:2). It is a heavenly cry; and the crier is not to be more precisely named. Isaiah 57:15”
