Except for Laish (Dan), Hazor is the only Palestinian settlement mentioned among the 25,000 cuneiform tablets that compose the royal documents of Mari or Tell Hariri located in modern Syria. Most of these documents connect with the reign of Zimri-Lim, a contemporary of the powerful King Hammurapi of Babylon in the 18th century BCE. So far, there are seven tablets related to Hazor. One of them reveals that Canaanite Hazor was so important that King Hammurapi saw convenient to place two ambassadors there. Other tablets associate Hazor with the trade of tin, for before the revolutionary introduction of iron, tin was essential for the manufacture of bronze weapons.
Joshua destroyed and burned the city of Hazor following his victory over the league of northern Canaanite cities at the "waters of Merom" (Joshua 11:1-11).
Hazor was assigned to the tribal territory of Naphtali (Joshua 19:36).
Deborah delivered Israel from the oppression of Jabin, King of Hazor and his general Sisera (Judges 4-5).
Solomon rebuilt Hazor and fortified it (I Kings 9:15).
The city of Hazor was captured and destroyed for the last time by the Assyrian king Tiglath-pileser III in 733 BCE (II Kings 15:29).
Strategically located to control the point where trade routes from the north, east and west joined to enter northern Canaan, it is no wonder that, in its heyday, Hazor covered more than 225 acres (making it more than twice the size of Megiddo) and its population numbered close to 40,000.
Texts from Mari (dated to the 18th century BCE) reveal that Hazor had close political and economic ties with Mesopotamia. One text refers to an ambassador of the great lawgiver, Hammurabi, as resident at Hazor, while another mentions Hazor's role in the trade of tin. From the time of the Egyptian New Kingdom (the beginning of the powerful Middle Kingdom 18th Dynasty) until the time of Rameses II, Hazor was a major military objective of those pharaohs who campaigned in Canaan.
