If any one owe a debt for a loan, and a storm prostrates the grain, or the harvest fail, or the grain does not grow for lack of water; in that year he need not give his creditor any grain, he washes his debt-tablet in water and pays no rent for this year.
If he do not receive a fixed rental for his field, but lets it on half or third shares of the harvest, the grain on the field shall be divided proportionately between the tiller and the owner.
