Isaiah 37:30-32

30“This shall be the sign [of these things] to you [Hezekiah]: you are to eat this year what grows of itself, and in the second year that which springs from the same, and in the third year you are to sow and harvest, and plant vineyards and eat their fruit.

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

32For out of Jerusalem will come a remnant and from Mount Zion a band of survivors. The zeal of the Lord of hosts will do this.” ’
