And he went forth unto the spring of the waters, and cast the salt in there, and said, Thus saith the LORD, I have healed these waters; there shall not be from thence any more death or barren land.

He slew of Edom in the valley of salt ten thousand, and took Selah by war, and called the name of it Joktheel unto this day.
