Isaiah 51:9,Awake, awake, put on strength, o arm of the Lord; awake as in the days of old, the generations of long ago. Was it not thou who cut Rahab in pieces, Who pierced the dragon ?.NASB The Rahab mentioned here is not the prostitute, rather, a monster of the sea with demonic strength. It seems that it is satan, as in Isaiah 51:9, it also mentions the dragon. So satan is also known as rahab. When I first read that Scripture I was confused until I researched a little further. Revelation 20:2, And he lay hold of the dragon, the serpent of old, who is the devil and satan, and bound him for a thousand years. NASB Here again, satan is refered to as the dragon. An aunt of one of daughters in law gave our grandson a toy dragon. I asked my daughter in law if she knew that satan is refered to as the dragon. She told me she did, I told her she should get rid of it. the last time I was at my sons home the dragon was still there. I decided not to mention it as I felt that the Holy Spirit would convict them to get rid of the dragon.
