After the condemnation of the priests of Noah, Abinadi returns to the positive aspects of the Messiah’s mission. There will come a time when “the salvation of the Lord shall be declared to every nation, kindred, tongue, and people.” The phrase “nation, kindred, tongue and people” is used in that order in Revelation 5:9, but the elements are also in Revelation 7:9 and 11:9. It shows up frequently in the Book of Mormon.
Verses 29 through 31 quote Isaiah 52:8–10, and were the final verses that the priests of Noah quoted when beginning Abinadi’s interrogation. Abinadi is tying up the threads of his explanation of the passages that the priests put to him. There is no chapter break at this point in the 1830 edition. Abinadi continues speaking without break in Mosiah 16.
