Eannatum made Umma a tributary, where every person had to pay a certain amount of grain into the treasury of the goddess Nina and the god Ingurisa

New Living Translation
Why should we die before your very eyes? Buy us and our land in exchange for food; we offer our land and ourselves as slaves for Pharaoh. Just give us grain so we may live and not die, and so the land does not become empty and desolate.”
