Job 38:37

Who can number the clouds in wisdom? or who can stay the bottles of heaven, Who can number the clouds in wisdom? or who can stay the bottles of heaven,

Who appoints by his wisdom the due measure of the clouds, accurately numbering the sum of vaporous particles (like so many grains of dust) of which they are to be composed? х shªchaaqiym (H7834), dust and clouds].

Stay - rather, empty-literally, lay down, or incline, so as to pour out х yashkiyb (H7901)].

Bottles of heaven - i:e., the rain-filled clouds.
