And the men of the city said unto Elisha, Behold, I pray thee, the situation of this city is pleasant, as my lord seeth: but the water is naught, and the ground barren. And he said, Bring me a new cruse, and put salt therein. And they brought it to him. 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. So the waters were healed unto this day, according to the saying of Elisha which he spake.
2 Kings 2:19-22 (King James Version)
Elisha’s Spring (also called the Prophet’s Fountain and Elisha’s Fountain) is a fresh water spring near the archaeological mound of Tel Jericho where remains of settlements were found dating back to about 8,000 BC. The people who settled here so long ago would have done so to take advantage of the fresh water which is such a scarcity in the harsh desert environment just north of the Dead Sea. Elisha’s Spring makes Jericho an oasis or City of Palms in the otherwise dry surroundings. The perennial spring continues to produce plenty of water which has a temperature of 26˚C.
