They can turn refuse to let you board if they wish, but I have heard from multiple frequent travelers that they really don't care. Overall El Al is known to be rather relaxed about official regulations as long as you aren't suspicious... Border control can also always issue you a shorter time period entry permit.
I have a friend that just arrived in Israel on a US passport that isn't good for 6 months and no one said anything to them at all.

According to travel.state.gov, the rule is somewhat vague:
Although the Israeli government does not require that a passport be valid for six months from the date of entry, airlines routinely do so and may decline boarding if a traveler has less than six months validity on his or her passport.
If you think there is a risk of being denied boarding by your airline, it might be worth trying to get a written statement from the airline stating their policy on passport validity. For example, if the rule they apply is "valid for six months from entry", then you're fine based on the date your passport expires. If the rule is "valid for six months from planned departure", then you're not. Once you get a written statement (as long as it means you can board), bring that with you to airline checkin in case there is any question.
Other unofficial pages have differing views on the topic. From goisrael.com:
All visitors to Israel must hold a passport that is valid for at least six months from the date they are departing the country.
From World Travel Guide:
To enter Israel, a passport valid for a minimum of six months from the date of entry is required by the nationals referred to in the chart above.
