“…the U.S. government has committed more than $5 billion in bilateral economic and non-lethal security assistance to the Palestinians, who are among the world’s largest per capita recipients of foreign aid.”
If you wish to know more about total US assistance to Palestinians, fiscal years 1990-2017, see the Congressional Research Service Report, “U.S. Foreign Aid to the Palestinians”, March, 2016. There are graphics and excellent detailed information about restrictions on allocated aid.
