The Testimony of Two Nations

2 Nephi 29:7–10

7 Know ye not that there are more nations than one? Know ye not that I, the Lord your God, have created all men, and that I remember those who are upon the isles of the sea; and that I rule in the heavens above and in the earth beneath; and I bring forth my word unto the children of men, yea, even upon all the nations of the earth?
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.
9 And I do this that I may prove unto many that I am the same yesterday, today, and forever; and that I speak forth my words according to mine own pleasure. And because that I have spoken one word ye need not suppose that I cannot speak another; for my work is not yet finished; neither shall it be until the end of man, neither from that time henceforth and forever.
10 Wherefore, because that ye have a Bible ye need not suppose that it contains all my words; neither need ye suppose that I have not caused more to be written.

President Joseph Fielding Smith said:

“This was spoken by prophecy to the gentiles of the present day. It should be remembered also, that the law given to Israel was that ‘the testimony of two men is true,’ providing they are honorable witnesses. Here the Lord applies the law to nations. Why should it not be so?

“If the word of the Lord is to be established by two chosen witnesses, then we may well look for two chosen nations to stand as witnesses for Jesus Christ. One such nation was Israel in Palestine, the other was Israel in America, Judah speaking from the Old World and Joseph from the New. Today these two testimonies for God and His truth have run together.”
