'T. B. S.' is quite right. I regret very much that I did not verify my quotation. A confusion of Og's bed and the lopping propensities of Adoni-Bezek seems to have decayed to the likeness of Procrustes. I have lived in this error for years. I have often used the image of King Og's bed in conversation and, I think, in published matter. No one has ever detected my slip, and it is by no means impossible that I am the centre of propagation of a mistake that will turn up again.
