"Baau. Bau. Bahu. Bohu. A Babylonian godess ; and according to the Greco-Phcenician legend (Sanchoniathon in Cory's Ancient Fragments) the wife of Kolpias ('the voice of the wind'). The name appears to be Semitic, signifying — like the Hebrew Bohu — 'space', or 'the void'. The Babylonians called her 'the eldest daughter of heaven', and she apparently the sky. The earth is said in Genesis (1,2) to have been tohu-va-bohu, 'formless and void', before creation began."
Catherine Keller, Professor of Constructive Theology at Drew University's "The Face of the Deep: A Theology of Becoming" 2003 "Bohu seems to be related to the Canaanite Baau, “goddess of the primal night, the mother of the first mortals.” p. 183 . https://books.google.ca/books?isbn=1134519222
