Isaiah 37:30-32

30"And this shall be the sign for you: this year you shall eat what grows of itself, and in the second year what springs from that. Then in the third year sow and reap, and plant vineyards, and eat their fruit.

31And the surviving remnant of the house of Judah shall again take root downward and bear fruit upward.

32For out of Jerusalem shall go a remnant, and out of Mount Zion a band of survivors. The zeal of the Lord of hosts will do this.
