Verse 2

During this jubilee Noah’s children began to fight one another, to take captives, and to kill one another; to shed human blood on the earth, to consume blood; to build fortified cities, walls, and towers; men to elevate themselves over peoples, to set up the first kingdoms; to go to war — people against people, nations against nations, city against city; and everyone to do evil, to acquire weapons, and to teach warfare to their sons. City began to capture city and to sell male and female slaves.
