These two verses are a summation of the two plus chapters of Isaiah (49:24–52:1) that Jacob has just quoted. Once more Jacob affirms that Isaiah’s prophecies are dual, referring to the several branches, or all of the house of Israel.
Jacob has emphasized in the previous chapters how the Lord’s covenants will be fulfilled with the Jews. His summary does the same. The ultimate filling of the Jewish covenant will be when they are “restored to the true church of God” (v. 2). To have the church restored tells us they once had a church among them. This was true before the meridian of time as shown when Zoram, Laban’s servant supposes that Nephi “spake of the brethren of the church” (1 Nephi 4:26). Stephen, the martyr, also taught in the New Testament, that Moses “was in the church in the wilderness” (Acts 7:38). However, the church will not be restored among the Jews until after or “when they shall be gathered home to the lands of their inheritance, and shall be established in all the lands of their inheritance” (v. 3). The plural usage of “lands” is interesting. It could refer to various areas within the land of Canaan, or it could refer to other lands away from Canaan. Nephi said later, “in the days that the prophecies of Isaiah shall be fulfilled men shall know of a surety, at the times when they shall come to pass” (2 Nephi 25:7). We will know about the “lands” question then, if not before.
There are six major points in Jacob’s sermon on the Atonement. The first major point follows.
