"Testimony of two"

1. John 8: 17
   17 It is also written in your law, that the testimony of two men is true.
2. 2 Ne. 29: 8
   8 Wherefore murmur ye, because that ye shall receive more of my word? Know ye not that the testimony of two nations is a witness unto you that I am God, that I remember one nation like unto another? Wherefore, I speak the same words unto one nation like unto another. And when the two nations shall run together the testimony of the two nations shall run together also.
