Shez lived to "an exceeding old age" (Ether 10:4), and in his old age "begat Riplakish," and Riplakish (apparently the youngest) reigned in his stead.
According to Hugh Nibley the name "Riplakish" (Ether 10:4) is a good archaic name, "lord of Lakish." There are at least five ancient cities named that. In fact, the oldest city in Mesopotamia is supposed to have been called Lakish. [Hugh W. Nibley, Teachings of the Book of Mormon, Semester 4, p. 252]
