The first half of the verse is missing in the King James Version; Nephi adds, “And again: Hearken, O ye house of Israel, all ye that are broken off and are driven out because of the wickedness of the pastors of my people; yea, all ye that are broken off, that are scattered abroad, who are of my people, O house of Israel.”
Isles means habitable ground or dry land as opposed to water, or in other words, islands and continents (see 2 Nephi 10:20–21).
America is referred to (see 1 Nephi 22:7–8).
“Called me from the womb”—that is, the servant was foreordained.
All servants of the Lord are foreordained (compare Jeremiah 1:5).
