The war with Sihon took place in the month of Elul. In the following month of Tishri they rested on account of the holy days, but immediately after these they set out to battle against Og. [682] This king did not hasten to his brother's aid, although he was only one day's distance from him, for he felt sure Sihon could conquer Israel without his assistance. [683] He erred in this, however, as in some other matters. In the war of the four kings against the five, it was Og who had brought to Abraham news of his nephew Lot's bondage, assuming that Abraham would surely hasten to his kinsman's aid, be killed in battle, and thus enable Og to get possession of the beautiful Sarah. God, however, leaves no man unrewarded or unpunished. To reward him for hastening with quick steps to advise Abraham of Lot's captivity, God granted him life for five hundred years, but he was eventually killed because it was only a wicked motive that had induced him to perform this service for Abraham. He did not, as he had hoped, gain Sarah, but was slain by her descendant Moses. [684] The battle against Og took place in Edrei, the outskirts of which Israel reached toward nightfall. On the following morning, however, barely at gray dawn, Moses arose and prepared to attack the city, but looking toward the city wall, he cried in amazement, "Behold, in the night they have built up a new wall about the city!" Moses did not see clearly in the misty morning, for there was no wall, but only the giant Og who sat upon the wall with his feet touching the ground below. [685] Considering Og's enormous stature, Moses' mistake was pardonable, for as a grave-digger of later times related, Og's thigh-bone alone measured more than three parasangs. "Once," so records Abba Saul, "I hunted a stag which fled into the thigh bone of a dead man. I pursued it and ran along three parasangs of the thigh-bone, yet had not reached its end." This thigh-bone, as was later established, was Og's. [686]
