The LORD shall save the tents of Judah first

Zechariah 12:7: The LORD also shall save the tents of Judah first, that the glory of the house of David and the glory of the inhabitants of Jerusalem do not magnify themselves against Judah.

Zechariah prophesied that Israel would be restored as a nation before Jerusalem was restored as a city.

Judah was conquered by the Babylonians in B.C. 606, and Jerusalem was sacked by the Babylonians in B.C. 588. A space of 19 years elapsed between these two events.

Israel became a nation in 1948, and the Jews regained full control of Jerusalem in the 1967 Six Day War. A space of 19 years also elapsed between these two events.
