Just 40 miles long and 10 miles wide, the Dead Sea is the world's lowest inhabitable spot on earth (1387 ft below sea level). At its deepest, it is over 1000 feet deep. The water is 8.6 times saltier than the ocean. Biblically, it was a place of refuge for King David. Herod the Great built his famous fortress, Masada, on the shore of the Dead Sea. 

Today, as in Jesus day, salt is harvested from the sea. In ancient time, salt was very valuable. It came in a loaf or small cake that had hardened on the ground. The salt was then pinched from top until the earth was revealed at the bottom of the loaf. When Jesus spoke about salt losing its flavor, he was referring to the salt that clings at the bottom of the loaf.

When floating the Dead Sea, little effort is needed to stay afloat. The water is rich in minerals and a said to have healing qualities. The minerals are used for everything from hand creams to fertilizers.

Genesis 14:1-3
1: And it came to pass in the days of Amraphel king of Shinar, Arioch king of Ellasar, Chedorlaomer king of Elam, and Tidal king of nations; 
2: That these made war with Bera king of Sodom, and with Birsha king of Gomorrah, Shinab king of Admah, and Shemeber king of Zeboiim, and the king of Bela, which is Zoar. 
3: All these were joined together in the vale of Siddim, which is the salt sea. 

Numbers 34:1-15
1: And the LORD spake unto Moses, saying, 
2: Command the children of Israel, and say unto them, When ye come into the land of Canaan; (this is the land that shall fall unto you for an inheritance, even the land of Canaan with the coasts thereof:) 
3: Then your south quarter shall be from the wilderness of Zin along by the coast of Edom, and your south border shall be the outmost coast of the salt sea eastward: 
4: And your border shall turn from the south to the ascent of Akrabbim, and pass on to Zin: and the going forth thereof shall be from the south to Kadesh-barnea, and shall go on to Hazar-addar, and pass on to Azmon: 
5: And the border shall fetch a compass from Azmon unto the river of Egypt, and the goings out of it shall be at the sea. 
6: And as for the western border, ye shall even have the great sea for a border: this shall be your west border. 
7: And this shall be your north border: from the great sea ye shall point out for you mount Hor: 
8: From mount Hor ye shall point out your border unto the entrance of Hamath; and the goings forth of the border shall be to Zedad: 
9: And the border shall go on to Ziphron, and the goings out of it shall be at Hazar-enan: this shall be your north border. 
10: And ye shall point out your east border from Hazar-enan to Shepham: 
11: And the coast shall go down from Shepham to Riblah, on the east side of Ain; and the border shall descend, and shall reach unto the side of the sea of Chinnereth eastward: 
12: And the border shall go down to Jordan, and the goings out of it shall be at the salt sea: this shall be your land with the coasts thereof round about. 
13: And Moses commanded the children of Israel, saying, This is the land which ye shall inherit by lot, which the LORD commanded to give unto the nine tribes, and to the half tribe: 
14: For the tribe of the children of Reuben according to the house of their fathers, and the tribe of the children of Gad according to the house of their fathers, have received their inheritance; and half the tribe of Manasseh have received their inheritance: 
15: The two tribes and the half tribe have received their inheritance on this side Jordan near Jericho eastward, toward the sunrising. 

Joshua 3:15-17
15: And as they that bare the ark were come unto Jordan, and the feet of the priests that bare the ark were dipped in the brim of the water, (for Jordan overfloweth all his banks all the time of harvest,) 
16: That the waters which came down from above stood and rose up upon an heap very far from the city Adam, that is beside Zaretan: and those that came down toward the sea of the plain, even the salt sea, failed, and were cut off: and the people passed over right against Jericho. 
17: And the priests that bare the ark of the covenant of the LORD stood firm on dry ground in the midst of Jordan, and all the Israelites passed over on dry ground, until all the people were passed clean over Jordan. 

Joshua 15:1-5
1: This then was the lot of the tribe of the children of Judah by their families; even to the border of Edom the wilderness of Zin southward was the uttermost part of the south coast. 
2: And their south border was from the shore of the salt sea, from the bay that looketh southward: 
3: And it went out to the south side to Maaleh-acrabbim, and passed along to Zin, and ascended up on the south side unto Kadesh-barnea, and passed along to Hezron, and went up to Adar, and fetched a compass to Karkaa: 
4: From thence it passed toward Azmon, and went out unto the river of Egypt; and the goings out of that coast were at the sea: this shall be your south coast. 
5: And the east border was the salt sea, even unto the end of Jordan. And their border in the north quarter was from the bay of the sea at the uttermost part of Jordan: 

Joshua 18:10-20
10: And Joshua cast lots for them in Shiloh before the LORD: and there Joshua divided the land unto the children of Israel according to their divisions. 
11: And the lot of the tribe of the children of Benjamin came up according to their families: and the coast of their lot came forth between the children of Judah and the children of Joseph. 
12: And their border on the north side was from Jordan; and the border went up to the side of Jericho on the north side, and went up through the mountains westward; and the goings out thereof were at the wilderness of Beth-aven. 
13: And the border went over from thence toward Luz, to the side of Luz, which is Bethel, southward; and the border descended to Ataroth-adar, near the hill that lieth on the south side of the nether Beth-horon. 
14: And the border was drawn thence, and compassed the corner of the sea southward, from the hill that lieth before Beth-horon southward; and the goings out thereof were at Kirjath-baal, which is Kirjath-jearim, a city of the children of Judah: this was the west quarter. 
15: And the south quarter was from the end of Kirjath-jearim, and the border went out on the west, and went out to the well of waters of Nephtoah: 
16: And the border came down to the end of the mountain that lieth before the valley of the son of Hinnom, and which is in the valley of the giants on the north, and descended to the valley of Hinnom, to the side of Jebusi on the south, and descended to En-rogel, 
17: And was drawn from the north, and went forth to En-shemesh, and went forth toward Geliloth, which is over against the going up of Adummim, and descended to the stone of Bohan the son of Reuben, 
18: And passed along toward the side over against Arabah northward, and went down unto Arabah: 
19: And the border passed along to the side of Beth-hoglah northward: and the outgoings of the border were at the north bay of the salt sea at the south end of Jordan: this was the south coast. 
20: And Jordan was the border of it on the east side. This was the inheritance of the children of Benjamin, by the coasts thereof round about, according to their families. 

死海-摩西和玛拉的水

死海含盐量太高，水中几乎没有生命。这使摩西想起玛拉水的苦水，那水是不能喝的。耶和华吩咐摩西把一棵树扔进去，苦水就变甜了，可以喝。人类也死了，但神加了基督，就像玛拉的那棵树，生命在基督里被赐下，灵魂得到医治和恢复。赞美耶和华！

出埃及记15:22-26

于是摩西领以色列人出了红海，到了书珥的旷野。他们在旷野走了三天，找不着水。到了玛拉，不能喝玛拉的水，因为水苦，所以那地名叫玛拉。百姓就向摩西发怨言，说，我们喝什么呢？他就呼求耶和华。,耶和华指示他一棵树,当他抛入水,水是甜的,有他为他们律例典章,他证明了他们,26日:说,你若努力听耶和华你的神,的声音,在他眼前要做正确的,愿意听从他的诫命,并保持他的律例,我将把这些疾病在你身上,我对埃及人带来的:因为我是耶和华,healeth你。
