On the morning of May 24, 1921, a force of eight hundred white policemen and soldiers confronted an African prophet, Enoch Mgijima, and some three thousand of his followers. Called the Israelites, they refused to leave their holy village of Ntabelanga, where they had been gathering since early 1919 to await the end of the world. While the Israelites maintained they were there to pray and worship in peace, the white authorities viewed them as illegally squatting on land that was not theirs. After many months of fruitless negotiations, the South African government sent an armed force to Bulhoek, a village in the Eastern Cape, to expel them. In the event that has come to be known as the Bulhoek massacre, police armed with rifles, machine guns, and cannons killed nearly two hundred Israelites wielding knobkerries, swords, and spears.

In The Finger of God, Robert Edgar reveals how and why the Bulhoek massacre occurred. Edgar asks: Why did Mgijima prophesize that the end of the world was imminent, and why did he summon his followers to Ntabelanga? Why did the South African government regard the Israelite encampment as a threat? Examining this clash between a government and a millenial movement, Edgar considers the Bulhoek massacre both as a signal event in South African history and as an example of similar conflicts worldwide.
