A) Is this verse talking about Mashiach, or to/about Israel?
B) What nation could possibly he/we not know?
C) I interpret the ‘nation’ mentioned in this verse to be Israel; the Mashiach did not/will not know of Jews, and Am Israel did not/would not know him… as the Moshiach is/will come from the other nations.
If you think about it, what better way to usher in unity between the Nations and Israel?
Is this a possible interpretation?
