Tehom

Tehom (Hebrew: תְּהוֹם təhôm) is a Northwest Semitic and Biblical Hebrew word meaning "the deep" or "abyss" (literally "the deeps"). It is used to describe the primeval ocean and the post-creation waters of the earth. It is a cognate of the Akkadian words tiāmtum and tâmtum as well as Ugaritic t-h-m which have similar meanings. According to a theological dictionary, tehom derives from a Semitic root which denoted the sea as a non-personified entity with mythological import.
