Yea, Egyptians vanity, and in vain do help, Therefore I have cried concerning this: `Their strength (rāḥāḇ ) to sit still. In Isaiah 30:7, rāḥāḇ (insolence, strength) becomes a proverbial expression that gives an allusion to the Hebrew etymology insolence. ( Psalm 89:8–10) YLT Awake, awake, put on strength, O arm of Jehovah, Awake, as days of old, generations of the ages, Art not Thou it that is hewing down Rahab (Egypt), Piercing a dragon! ( Isaiah 51:9) YLT Insolence With the arm of Thy strength Thou hast scattered Thine enemies. Thou hast bruised Rahab (Egypt), as one wounded. ( Psalm 87:4) YLT Thou art ruler over the pride of the sea, In the lifting up of its billows Thou dost restrain them. I mention Rahab (Egypt) and Babel to those knowing Me, Lo, Philistia, and Tyre, with Cush! This was born there. However, there is nothing revealing in the Coptic language. It might have Egyptian origins that were accommodated to the Hebrew language. They believed that the sun was covered because the Leviathan used to eat it for that period of time. The Leviathan was believed, by ancient people, to be the cause of solar eclipses. Hittite myths contain accounts of a battle between the weather god and the dragon Illuyankas, and the Babylonians told of a fight between their god Marduk and the monster Tiamat. A Canaanite poem from Ras Shamra (ancient Ugarit) in northern Syria records a battle between the god Baal and another monster called Leviathan. Scattered through the Prophets and Holy Writings (the two latter portions of the Hebrew Bible) are allusions to ancient myths whose origins may well be outside of the Judaic tradition- for instance the primordial combat between Yahweh and a monster variously named Leviathan, Rahab, or simply Dragon.
