So is your firmament solid? How can birds fly in a solid dome?
What does the Hebrew word actually mean? The Hebrew noun
raqia is derived from the verb
raqa, which means “to spread abroad, stamp, or stretch.
Many other verses, such as
Psalm 104:2 and
Isaiah 40:22, speak of the stretching out of the heavens. The Hebrew word used in these verses for heaven is not
raqiya, but
shamayim (literally “heavens”). However, in
Genesis 1:8 God explicitly calls the expanse “heaven,” thus equating
raqiya with
shamayim. If the stretched out nature of the
raqiya is what is intended, then
firmament may not be the best translation;
expanse is more accurate.
