Why should they? The Palestinians are living on their OWN land. It's NOT part of israel.
Arab countries know from the Nakba that once Palestinians are forced off their OWN land, and become refugees in another country israel will never let them return to their OWN land.
AS for not giving them necessities of life it's all parked outside Gaza because the israelis won't let it in. You know that, don't you?

Scorecard: Israel Fails to Comply with U.S. Humanitarian Access Demands in Gaza
November 12, 2024
Executive Summary
Despite intensive diplomatic engagement by the United States and other countries, Israel has consistently failed to uphold its legal obligation to facilitate adequate humanitarian relief for civilians in Gaza during its ongoing military operation there. People are being starved in Gaza: Israeli military operations have denied them critical food aid and basic necessities, which has, in turn, caused conditions approaching famine for 800,000 Palestinian civilians across Gaza. Conditions are worst in Gaza’s north, where Israel launched a major operation in October that has cut off humanitarian aid to the area.
