"The number of whom"

1. Rev. 20: 8
     8 And shall go out to deceive the nations which are in the four quarters of the earth, Gog and Magog, to gather them together to battle: the number of whom is as the sand of the sea.
2. Alma 24: 28
     28 Now the greatest number of those of the Lamanites who slew so many of their brethren were Amalekites and Amulonites, the greatest number of whom were after the order of the Nehors.
