3 Nephi 10:14-17

14And now, whoso readeth, let him understand; he that hath the scriptures, let him search them, and see and behold if all these deaths and destructions by fire, and by smoke, and by tempests, and by whirlwinds, and by the opening of the earth to receive them, and all these things are not unto the fulfilling of the prophecies of many of the holy prophets.

15Behold, I say unto you, Yea, many have testified of these things at the coming of Christ, and were slain because they testified of these things.

16Yea, the prophet Zenos did testify of these things, and also Zenock spake concerning these things, because they testified particularly concerning us, who are the remnant of their seed.

17Behold, our father Jacob also testified concerning a remnant of the seed of Joseph. And behold, are not we a remnant of the seed of Joseph? And these things which testify of us, are they not written upon the plates of brass which our father Lehi brought out of Jerusalem?
