Isaiah 37:30-32

37:30 “This will be your reminder that I have spoken the truth: This year you will eat what grows wild, and next year what grows on its own. But the year after that you will plant seed and harvest crops; you will plant vines and consume their produce. 37:31 Those who remain in Judah will take root in the ground and bear fruit.

37:32 “For a remnant will leave Jerusalem;

survivors will come out of Mount Zion.

The intense devotion of the Lord who commands armies will accomplish this.
