Yeshayah 59:19-21 Orthodox Jewish Bible (OJB)
19 So shall they fear the Shem Hashem from the ma’arav (west), and His kavod from the rising of the shemesh. When the enemy shall come in like a nahar (flood, river), the Ruach [Hakodesh] of Hashem shall lift up a standard against him.
20 And the Go’el (Redeemer, Moshiach) shall come to Tziyon, and unto them that make teshuva and turn from peysha (rebellion) in Ya’akov, saith Hashem [See Ro.11:26 OJBC].
21 As for Me, this is My Brit (Covenant, [see Isaiah 42:6; 49:8; 54:10; 55:3]) with them [i.e., with Moshiach’s zera, see Isaiah 53:10], saith Hashem; My Ruach [Hakodesh] that is upon thee [Moshiach, see Isaiah 11:2; 42:1; 48:16; 61:1], and My words which I have put in thy mouth, shall not depart out of thy mouth, nor out of the mouth of thy zera [Isaiah 53:10], nor out of the mouth of the zera of thy zera [i.e. Moshiach’s zera generationally], saith Hashem, from henceforth and ad olam (forever).
