John Trapp on Job 38:25

Who hath divided (or derived) a water courſe for the over-flowing of waters?] That is, the water-clouds for the powring out of raine, Velut per canales & tubulos; as by Pipes and conveyances whereſoever God pleaſeth, men being amazed at thoſe miracles of Nature, Is it not the Lord alone? He it is who divideth the Deluge of waters; as it were draining them into certain furrowes which would otherwiſe fall down from heaven all at once, and make great ſpoil here below.

Or a way for the lightning of thunder] Nimbo ſonoro, ſaith Tremellius. See chap 28.6. with the Note.
