" Seely shows how the modern scientific bias has guided the translators to render the word for “firmament” (raqia) as “expanse.” Raqia in the Bible consistently means a solid material such as a metal that is hammered out by a craftsman (Ex. 39:3; Isa. 40:19). And when raqia is used elsewhere in the Bible for the heavens, it clearly refers to a solid material, sometimes even metal! "
