We saw in the discussion of Mosiah 14:10/Isaiah 53:10 that there are multiple ways in which Isaiah's use of "generation" can be seen, ranging from looking back to ancestors, to a declaration about his contemporaries, and finally pointing forward to his descendants. Regardless of how we might read Isaiah, Abinadi clearly reads this as descendants. He has powerful reasons for wanting to do so, as by declaring that this use of "generation" parallels the idea of the atoning Messiah seeing his seed he can focus the attention of his discourse on that seed.
Poetic: It is possible that Abinadi is obliquely relating the sowing of seed to publishing peace. He will end this part of the discourse with a return to the question he was asked. By the time he returns, the seed and the publishing have become the same thing. Perhaps in Abinadi's language there is some underlying word play that relates seeds to publishing. The concepts of creation through broadcasting are sufficiently similar, particular to an agricultural people.
