Both are part of the economic and psychological war of attrition Israel is waging against Palestinians and their leadership
Israel steals hundreds of millions of shekels each month from the Palestinian Authority. These are the customs on imported goods destined for Palestinians that pass through Israeli ports, and the taxes and tariffs on fuel, cigarettes, and cement that Israel sells to the Palestinians. Instead of transferring these revenues to PA treasury officials as it is required to do, it deposits the funds into some Israeli account.
