2 Kings 19:31

For out of 3erusalem shall go forth a remnant, and they that escape out of Mount Zion, this being the capital and center of the Old Testament Church. The zeal of the Lord of hosts shall do this. There is a Messianic thought underlying the prophet's words, of the deliverance of the daughter of Zion, of those chosen by the Lord, to be kept by His power throughout eternity. The Lord now pronounces His decree in the crisis which was upon Judah-Jerusalem.
