2 Kings 19:29-32

29‘Then this shall be the sign [of these things] to you [Hezekiah]: this year you will eat what grows of itself, in the second year what springs up voluntarily, and in the third year sow and reap, plant vineyards, and eat their fruit.

30The survivors who remain of the house of Judah will again take root downward and bear fruit upward.

31For a remnant will go forth from Jerusalem, and [a band of] survivors from Mount Zion. The zeal of the Lord of hosts shall perform this.

32‘Therefore thus says the Lord concerning the king of Assyria: “He will not come to this city [Jerusalem] nor shoot an arrow there; nor will he come before it with a shield nor throw up a siege ramp against it.
