'Vault' in the Bible

‘Thick clouds are a hiding place for Him, so that He cannot see,And He walks on the vault (circle) of the heavens.’

It is He who builds His upper chambers in the heavensAnd has established His vaulted dome (the firmament of heaven) over the earth,He who calls to the waters of the seaAnd pours them out on the face of the earth—The Lord is His name.
