John Trapp on Job 37:12

Verſe 12 And it is turned round about by his counſel] Vertit Dominus & revertit. The Lord turneth and returneth: letteth out, and bringeth back the clouds, as it were by a rope, at his own pleaſure: a Metaphor from Mariners, who skilfully manage the ropes of the Ship to beſt advantage. In like ſort the clouds are, by Gods cunning turned about in a circuit (as Beza rendreth it) that is in a round compaſſe or circle; they are not carried up and down the aire by and wandring and inconſtant motion: but they are, as it were, by certain Engines (ſo he maketh the Metaphor) of Almighty God, turned about at his own pleaſure, when and where he thinketh good to uſe them; for he beſt knoweth where is moſt need of raine, ſnow, &c. and therefore he by his wiſdome driveth them hither and thither, for the fulfilling of his purpoſe. Some refer this Text to the revolution of the Heavenly Orbs; which is alſo done by God.

That they may do whatſoever he commandeth them] A Metaphor like that Levit. 25.21. where God ſaith that he will command his bleſſing upon the ſixth year; and it ſhall bring forth fruit for three years. Now if the ſenſeleſs creatures ſo readily obey God, how much more ſhould we? And if he be Lord of Tempeſts, he is alſo of Diſeaſes and diſaſters. Chear up therefore, and ply the throne of Grace. He will ſee that all ſhall go well with his ſuppliants.
