They apparently use a “proportional representation” system, where you vote for the party, not any particular candidate. If a party gets X% of the vote, it gets to appoint roughly X% of the seats.

The problem with multi-party parliaments (like in most of the world) is if you have lots of little parties, and a narrow majority, all it takes is for one of the little parties to pull out of your coalition, and your government falls.
Other parliamentary systems have geographic districts. Citizens have a go-to that has a stake in representing that constituent against obnoxious bureaucrats. Not so in Israel. “Proteczia”.
