In his inscription - see MOABITE STONE - Mesha gives an account of his rebellion, naming the places captured and fortified by him. It is not surprising that he says nothing of his defeat by Jehoram and his allies. There is, however, one serious discrepancy. The time Moab was under the supremacy of Israel, during the reign of Omri and half the reign of Ahab, he puts at 40 years. According to Biblical chronology, Omri and Ahab together reigned only 34 years. If, with Mesha, we deduct half the reign of Ahab, the period is reduced to 23 years. It is impossible to add to the length of either reign. So great a difference cannot be explained by the use of round numbers. Why Mesha should wish to increase the time of his people's subjection is not clear, unless, indeed, he thought in this way to magnify the glory of their deliverer.
In Mesha the sentiment of patriotism was wedded to some measure of military capacity. Judging by his inscription, he was also a deeply religious man according to his lights. Substitute “Yahweh†for “Chemosh,†and his phraseology might be that of a pious Hebrew king. The sacrifice of his son is at once the mark of the heathen and an index of the strength of his devotion.
