Isaiah 37:30-32 KJV

"And this shall be a sign unto thee, Ye shall eat this year such as groweth of itself; and the second year that which springeth of the same: and in the third year sow ye, and reap, and plant vineyards, and eat the fruit thereof. And the remnant that is escaped of the house of Judah shall again take root downward, and bear fruit upward: For out of Jerusalem shall go forth a remnant, and they that escape out of mount Zion: the zeal of the LORD of hosts shall do this."

27
Therefore their inhabitants were of small power, they were dismayed and confounded: they were as the grass of the field, and as the green herb, as the grass on the housetops, and as corn blasted before it be grown up.*
28
But I know thy abode, and thy going out, and thy coming in, and thy rage against me.*
29
Because thy rage against me, and thy tumult, is come up into mine ears, therefore will I put my hook in thy nose, and my bridle in thy lips, and I will turn thee back by the way by which thou camest.
30
And this shall be a sign unto thee, Ye shall eat this year such as groweth of itself; and the second year that which springeth of the same: and in the third year sow ye, and reap, and plant vineyards, and eat the fruit thereof.
31
And the remnant that is escaped of the house of Judah shall again take root downward, and bear fruit upward:*
32
For out of Jerusalem shall go forth a remnant, and they that escape out of mount Zion: the zeal of the LORD of hosts shall do this.*
33
Therefore thus saith the LORD concerning the king of Assyria, He shall not come into this city, nor shoot an arrow there, nor come before it with shields, nor cast a bank against it.
34
By the way that he came, by the same shall he return, and shall not come into this city, saith the LORD.
35
For I will defend this city to save it for mine own sake, and for my servant David’s sake.
