Critics often cite Psalm 150:1 ("...praise him in the firmament of his power") to argue that the Bible teaches a solid, structural sky dome.

The word here which is rendered "firmament" is the Hebrew raqiya, which properly means an expanse. Indications from contextual and linguistic studies are that this raqiya is not the solid structure that the English word "firmament" implies, but rather a metaphorical or phenomenological description of the sky's vast expanse.
