Isaiah 43:19

“Behold, I will do a new thing, &c.] A wonderful and unheard of thing, and therefore introduced with a “behold”, as a note of admiration; the same with the new thing created in the earth, (<243122>Jeremiah 31:22), the incarnation of the Son of God; who took flesh of a virgin, appeared in the likeness of sinful flesh, and was made sin and a curse for his people, in order to obtain eternal redemption for them; which blessing, though not newly thought of, resolved on, contrived, and agreed upon, that being from eternity; nor newly made known, or as to the virtue and efficacy of it, which had been from the beginning of the world, yet new as to the impetration of it by the blood and sacrifice of…”

Isaiah 43:20”

“I will do: Isa 42:9, Isa 48:6; Jer 31:22; Rev 21:5 I will even: Isa 35:6-10, Isa 40:3, Isa 40:4, Isa 48:21; Luk 3:4, Luk 3:5 rivers: Isa 41:18, Isa 48:21, Isa 48:22; Exo 17:6; Num 20:11; Deu 8:15; Psa 78:16-20, Psa 105:41 Isaiah 43:20”
