Zechariah 12 - 13

Zechariah 12-13, often studied piecemeal, are co-extensive prophecies that talk about the protection of Israel during the time when nations of the world would attack them. The prophecy refers to a time after the Romans conquered and scattered the Jews, a point where they were no longer able to remove Jerusalem. The prophecy ends in chapter 13 with the purification trials of the people, purging of the priesthood, and the statement that "This people" will say "The Lord God".  These prophecies are relevant to understand several aspects of the New Testament, especially with regard to purifying the sons of Levi and creating a new priesthood.
