Ezekiel 5:2; Ezekiel 5:12

2 When the days of your siege come to an end, burn a third of the hair inside the city. Take a third and strike it with the sword all around the city. And scatter a third to the wind. For I will pursue them with drawn sword.

12 A third of your people will die of the plague or perish by famine inside you; a third will fall by the sword outside your walls; and a third I will scatter to the winds and pursue with drawn sword.
