nThe word translated ÔskyÕ or ÔskiesÕ here is
Ôshahaq.Õ
nIt occurs 21x in the Bible.
nThe dictionary lists the main meanings as ÔdustÕ and ÔcloudÕ; ÔskyÕ is only given as a secondary meaning under Ôcloud.Õ
nElihu uses the word 3 other times, always translated Ôcloud.Õ
nI suggest we try ÔcloudÕ here, too.
