The Prophet, naturally, wondered how long this condition was to last, and the Lord answered his humble question in these closing verses of the chapter: Until the cities and homes be depopulated, the land utterly desolate, and the people driven into exile. But, (v. 13), a remnant, a tenth part, would be left, and return. This remnant is a "holy seed."
"For I would not, brethren, that ye should be ignorant of this mystery, lest ye should be wise in your own conceits; that blindness in part is happened to Israel, until the fulness of the Gentiles be come in, and so all Israel shall be saved: as it is written. These shall come out of Zion the Deliverer, and shall turn away ungodliness from Jacob." (Paul, 26)
