Intertextual Connections between Helaman 5 and Mosiah 4 -- Nephi and Lehi recall their father Helaman quoting King Benjamin.

In Helaman 5:9, Nephi and Lehi recall the words of their father Helaman, who invited them to remember the words of King Benjamin:

9 O remember, remember, my sons, the words which king Benjamin spake unto his people; yea, remember that there is no other way nor means whereby man can be saved, only through the atoning blood of Jesus Christ, who shall come; yea, remember that he cometh to redeem the world.

These words can be found in Mosiah 4:7-8, about 95 chapters earlier in the text:

7 I say, that this is the man who receiveth salvation, through the atonement which was prepared from the foundation of the world for all mankind, which ever were since the fall of Adam, or who are, or who ever shall be, even unto the end of the world.
8 And this is the means whereby salvation cometh. And there is none other salvation save this which hath been spoken of; neither are there any conditions whereby man can be saved except the conditions which I have told you.
