Israel's Knesset is considering a bill that would make it tougher for the government to give up land in a peace deal.

The first reading of the land-for-peace bill passed the Israeli parliament, Wednesday, by a 68-22 vote.

The legislation would require the country hold a national vote to turn over any annexed by Israel. 
    
That would include the Golan Heights and east Jerusalem-- areas under Israeli sovereignty, but claimed by Syria and the Palestinians.

The Knesset must approve two more readings of the bill before it becomes law.
