11. only Og king of Bashan remained of the remnant of giants--literally, "of Rephaim." He was not the last giant, but the only living remnant in the trans-jordanic country (Jos 15:14), of a certain gigantic race, supposed to be the most ancient inhabitants of Palestine.
      behold, his bedstead was a bedstead of iron--Although beds in the East are with the common people nothing more than a simple mattress, bedsteads are not unknown. They are in use among the great, who prefer them of iron or other metals, not only for strength and durability, but for the prevention of the troublesome insects which in warm climates commonly infest wood. Taking the cubit at half a yard, the bedstead of Og would measure thirteen and a half feet, so that as beds are usually a little larger than the persons who occupy them, the stature of the Amorite king may be estimated at about eleven or twelve feet; or he might have caused his bed to be made much larger than was necessary, as Alexander the Great did for each of his foot soldiers, to impress the Indians with an idea of the extraordinary strength and stature of his men [LE CLERC]. But how did Og's bedstead come to be in Rabbath, of the children of Ammon? In answer to this question, it has been said, that Og had, on the eve of engagement, conveyed it to Rabbath for safety. Or it may be that Moses, after capturing it, may have sold it to the Ammonites, who had kept it as an antiquarian curiosity till their capital was sacked in the time of David. This is a most unlikely supposition, and besides renders it necessary to consider the latter clause of this verse as an interpolation inserted long after the time of Moses. To avoid this, some eminent critics take the Hebrew word rendered "bedstead" to mean "coffin." They think that the king of Bashan having been wounded in battle, fled to Rabbath, where he died and was buried; hence the dimensions of his "coffin" are given [DATHE, ROOS].
