And the land shall mourn
That is, the inhabitants of it; not only Jerusalem, but the land of Judea, and the people in it everywhere: in the Talmud F15 it is said, this is the mourning of the Messiah, that is, on his account:
every family apart;
though the mourning will be general and public, yet it will be not in a body of the whole people together, but separate and distinct:
the family of the house of David apart, and their wives apart;
the men by themselves, and the women by themselves, which is according to the custom of the Jews in public worship; those that belong to the family of David shall mourn because of the Jews' long rejection of the King Messiah, Jesus the son of David, the Saviour, whom God raised up of his seed:
the family of the house of Nathan apart, and their wives apart;
not of Nathan the son of David, the brother of Solomon, as some think; for, as Aben Ezra observes, he and his family are comprehended in the family of David; but of Nathan the prophet, who will mourn because the Jews have so much slighted Jesus the great Prophet, the Lord raised up in Israel, his doctrines and ordinances.
F15 T. Hieros. Succah, fol. 55. 2.
