My mountain in the field, I will give your substance and all your treasures for a plunder, and your high places, because of sin, throughout all your borders.

For he will be as a tree planted by the waters, who spreads out its roots by the river, and will not fear when heat comes, but its leaf will be green; and will not be concerned in the year of drought. It won’t cease from yielding fruit.
