2 Nephi 6

2 Nephi 6:4 And they are the words which my brother has desired that I should speak unto you. Was Jacob here, trying to bolster his authority or add weight to his words by saying, "Nephi also thinks this is important"? Or was he saying it in the way a high councilor says, "This is what the Stake Presidency has asked me to focus on"?

6:5 They may be likened unto you, for ye are of the house of Israel." This is interesting: he doesn't say they are actually about you because you are of the house of Israel, bur they can be likened unto you. Am I misunderstanding what he means by liken? Probably. Except he then goes on to talk about the scattering and returning of the Jewish nation, still inhabiting the area known as Israel.
Additionally, how many of the prophesies regarding the children of Israel are actually, as we are also (either through literal descent or adoption) of the house of Israel?

6:9 They should return again...and...the Holy One of Israel should manifest himself unto them in the flesh; This just made me think and question when the kings should be the nursing mothers and fathers. I had always read that to be a prophesy focused on the second coming and the literal gathering of Israel, not the return of the tribe of Judah from Babylonian captivity, as this seems to be saying. If I'm understanding Jacob's commentary, he's saying that they get scattered, and then they return (with kings and queens as nursing parents), and then Christ appears to them and they get smitten and afflicted.

6:10 And after they have hardened their hearts and stiffened their necks against the Holy One of Israel, behold, the judgments of the Holy One of Israel shall come upon them. And the day cometh that they shall be smitten and afflicted. Were the jews persecuted for thousands of years because they crucified Christ? Was their treatment throughout Europe throughout the dark ages a punishment from God or natural animosity toward foreign businessmen? Is there any chance that this scripture is saying that the Holocaust was a punishment for two thousand year old choices? I think not. I think the scattering that occurred for hundreds of years may be attributed to that, but I think that he prophesy is focused on "scattered" and "gathered." What happens in between isn't part of the punishment.

6:13 For the people of the Lord are they who wait for him; for they still wait for the coming of the Messiah. This is interesting, because currently the Jews say that Jesus was not the Messiah because he failed to fulfill some of Isaiah's prophecies - a very valid argument - and so they are still waiting for someone who will meet the criteria and prove himself to be the promised Messiah. We (conveniently) accept Jesus as the Christ, despite those unfulfilled prophecies, by saying that he'll fulfill the rest the next time he shows up. If I were looking for a man behind the curtain, I would start pointing.
