Lalu keluarlah seorang pendekar dari perkemahan orang Filistin, namanya Goliat, dari Gat. Tingginya enam hasta sejengkal.

Bereshit Rabbah 76, which tells about the two people who had been reassured by G'd, -Jacob and Moses,- refers to the fact that both of them seem to have harboured feelings of fear immediately prior to their respective encounters with Esau or Og. The truth is that neither one of them had really been afraid, they had only acted as if they had been afraid. One cannot order someone to become fearless. Fear is a natural attitude, not subject to legislation. However, when a person adopts a posture of fear, he can be instructed by G'd to abandon such a posture. So Jacob and Moses were told to adopt a posture of confidence also vis a vis their own people and to inspire them in this manner. The Talmud, of course, ascribes Og's confidence to the fact that he had been able to survive the deluge. He was believed to have been able to have done so due to his own merit already in the days of Abraham. Later on he had been instrumental in activating Abraham's pursuit of the kings who had taken Lot prisoner. The reason the Torah lists the measurements of Og's bedstead, is to explain why he had survived the deluge. It had not been due to any special merit but had been due to his size. He was one and a half times the height of the giant Goliath.
