Through the Canaanitish colonies in Babylonia a knowledge of Babylonian law was necessarily communicated to the commercial world of the West. Moreover, Babylonian rule brought with it Babylonian culture and law as well. The ‘Amorites’ when the Babylonians first met with them were doubtless in a semi-barbarous condition, and their subsequent culture, as we now know, was wholly Babylonian. A very important part of this culture, at all events in the eyes of the trading world, was the law of Babylonia, more especially in its relation to contracts. That the purchase of the field of Machpelah should have been conducted with all the formalities to which Abraham had been accustomed in his Chaldæan home, is consequently what archæological discovery has informed us ought to have been the case. A simple form of contract for the sale and purchase of landed property in Babylonia is to be found in one that was drawn up in the reign of Eri-Aku or Arioch. It is written in Sumerian, the old legal language of Chaldæa, as Latin was the legal language of Europe in the Middle Ages, and runs as follows:—‘One and five-sixths _sar_[68] of a terrace with a house upon it, bounded on three sides by the house of Abil-Sin, and on the fourth side by the street, has been purchased by Sin-uzilli the son of Tsili-Istar from Sin-illatsu the son of Nannar-arabit: 2-½ shekels of silver he has weighed as its full price. In days to come Sin-illatsu shall never make any claim in regard to the house or dispute the title. The (contracting parties) have sworn by the names of Sin, Samas, and king Eri-Aku. Witnessed by Abu-ilisu the son of Tsili-Istar, Abil-Sin the son of Uruki-bansum, Nur-Amurri the son of Abi-idinnam, Ibku-Urra, son of Nabi-ilisu, and Sin-semê his brother. The seals of the witnesses (are attached).’[69]
