we would have quickly become like Sodom,

we would have become like Gomorrah.

14:30 The poor will graze in my pastures;

the needy will rest securely.

But I will kill your root by famine;

it will put to death all your survivors.

37:32 “For a remnant will leave Jerusalem;

survivors will come out of Mount Zion.
