The surface of the Dead Sea is hundreds of meters below sea level so it seems like pumping would only be needed to prime a siphon and then it could keep flowing. What am I missing?

A siphon is powered by air pressure on the surface of the source and can only lift water as far as the available pressure pushes it. That’s about 10 meters for atmospheric pressure, no matter how much vacuum you pull on the other side. If the route requires lifting more than that along the way, the siphon would not work at all.
