The Promised Land and in particular mount Zion was considered to be God’s territory. As much as God was interested in protecting and preserving his people, he was also interested in maintaining possession of the city of Jerusalem. Knowing the Assyrians intended to capture and take possession of Judah’s capital, Isaiah declared, “So shall the LORD of hosts come down to fight for mount Zion, and for the hill thereof. As birds flying, so will the LORD of hosts defend Jerusalem; defending also he will deliver it; and passing over he will preserve it” (Isaiah 31:4-5).

The terms defend  and deliver were typically used in connection with God’s people, but in the case of mount Zion, or as it was also known as, Jerusalem, God’s resources would be expended to retain a territory dedicated to his Messiah. Zion was mentioned throughout the book of Isaiah appearing in 31 of its 66 chapters. Clearly Isaiah saw Zion as a critical element of his prophecy about Israel’s future. The significance of Zion was both its geographical location and its purpose as a worship center for the entire world. According to Isaiah, the LORD founded Zion (Isaiah 14:32) and would reign there after his judgment of the world for universal sin (Isaiah 24:23).

Although the importance of mount Zion was connected to God’s people, the LORD’s protection of it was independent of their situation. God intended to personally defend his territory (Isaiah 31:4) in spite of his children’s rebellion. In fact, the LORD told Isaiah, “Now go, write it before them in a table, and note it in a book, that it may be for the time to come for ever and ever: that this is a rebellious people, lying children, children that will not hear the law of the LORD” (Isaiah 30:8-9).

Eventually, Jerusalem would fall into enemy hands (2 Kings 25:4), but not to the Assyrians. God would miraculously deliver Jerusalem from king Sennacherib of Assyria in 701 B.C. and delay the city’s destruction for more than a hundred years, allowing the people of Judah to escape Assyrian captivity and end up instead in Babylon. Isaiah described the Assyrian attack as punishment for the Judah’s rebellion.

Wherefore thus saith the Holy One of Israel, because ye despise this word and trust in oppression and perverseness, and stay thereon: therefore this iniquity shall be to you as a breach ready to fall, swelling out of a high wall, whose breaking cometh suddenly at an instant. And he shall break it as the breaking of the potters’ vessel that is broken in pieces; he shall not spare. (Isaiah 30:12-14).
