After the Hebrews left Egypt, they encountered the Egyptian Pharaoh's pursuing army at the Red Sea. The prophet Moses prayed for divine power, and the Red Sea parted, allowing the Hebrews to cross to the other shore. Afterward, they came to Canaan, called in the Old Testament a land of bliss, the "Promised Land," the "Land of Hope," supposedly a fertile place "flowing with milk and honey."

Not long after leaving Egypt, some of them began to regret it, endlessly complaining about the lack of water and food. Their journey toward Sinai was a road of complaints, yet God still favored them and opened a path for them.

They wandered in the wilderness for three days before reaching Marah, where they could not drink the water because it was bitter. That was why the place was called Marah.

The people complained to Moses, saying, "What are we supposed to drink?"

Moses cried out to Jehovah, and Jehovah showed him a tree. He threw the tree into the water, and the water became sweet.

Venice was built on coastal shallows, a small island connected to the mainland by bridges. Seawater could not be drunk, so drinking water was piped in from the mainland.

Thus, they did not need to devote themselves to developing seawater desalination technology due to water shortages, like the Arabs.

Seawater was the most abundant and stable of all water sources, but it was bitter and brackish, impossible to drink directly. How wonderful it would be if seawater could be desalinated.

Science had helped people improve their lives, and seawater desalination had become a reality. In some places,
