But the miry places thereof and the marishes thereof shall not be healed; they shall be given to salt.
The marishes ... shall not be healed; they shall be given to salt - "marishes," marshes. The region is known to have such pits and marshes. The Arabs take the salt collected by evaporation in these pits for their own use, and that of their flocks.
Not be healed. Those not reached by the healing waters of the Gospel, through their sloth and earthly-mindedness, are given over to their own bitterness and barrenness (as "saltness" is often employed to express, Deuteronomy 29:23; Psalms 107:34, "barrenness" - margin, saltness; Zephaniah 2:9; Revelation 22:11, "He that is unjust, let him be unjust still; and he which is filthy, let him be filthy still;" an awful example to others in the punishment they suffer; 2 Peter 2:6).
