Yeshayahu 55:5 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?
