the Israelis want a monotheistic state

No, they want and have created a secular state where any religion can be practised. Unusual for that region.

Ben Gurion recognised that - that is why he said what he said.

David Ben-Gurion expressed his concern about the Arab fellahin, whom he viewed as "the most important asset of the native population." Ben-Gurion said "under no circumstances must we touch land belonging to fellahs or worked by them." He advocated helping liberate them from their oppressors. "Only if a fellah leaves his place of settlement," Ben-Gurion added, "should we offer to buy his land, at an appropriate price."
