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?

My guess is pumping losses. Essentially there’s friction moving water through a pipe, and the distance would be so long as to make said friction higher than the available suction. It would probably just start cavitating and destroy the pipe.
yea, your pipe friction is refered to as ‘major losses’, and on a system that long would be >> than head. Would definitly need to pump!
Also, the maximum pressure you could have enough siphon is the difference in air pressure between the two ends. If you want more pressure, you have to pump.
