John Trapp on Job 37:15

Verſe 15. Doſt thou know when God diſpoſed them?] Viz. Thoſe wondrous works of God in the Aire eſpecially; thoſe varieties of Meteors, the generation and motions whereof, the greateſt Philoſophers cannot perfectly find out by their natural cauſes, neither do they wel agree amongſt themſelvs concerning thoſe cauſes. For Anaximander holdeth one thing, Metrodorus another, Anaxagoras a third, Ariſtotle a fourth; let thoſe that have a mind to it, read their janglings and Diſputes in Plutarch, De placitis Philoſophorum. Now if no man (though never ſo wiſe) can underſtand the wondrous works of God in theſe common things of Nature; how can he comprehend his hidden works, hoc eſt, crucem, ſaith Brentius?

And cauſed the light of his cloud to ſhine] Or, That he may cauſe the light of his cloud to ſhine. Hereby he meaneth lightnings, iſſuing out of the moiſt and cold cloud ſay ſome, the Rainbow, ſay others, that wonderful work of God (fained therefore by the Heathens to be the daughter of Thaumantias, Plato. or of wonderment) which is full of wonders, witneſſe the beautiful ſhape thereof, and various colours, with their ſeveral ſignifications, as ſome conceive: the ſeveral Prognoſticks; viz. Of rain in the morning, of fair weather in the evening, as Scaliger concludeth; the form of it a bow, which yet never ſhooteth any man unleſſe it be with aſtoniſhment and love, &c. God puts his bow in his hand (ſaith Ambroſe on Geneſ. 9.13) not his arrow, but his bow, and the ſtring of the bow is to us-ward. The Jewes conceit that the name Jehovah is written on the Rainbow, and therefore they no ſooner ſee it, but they hide their eyes, confeſſe their ſins that deſerve a ſecond deluge) celebrate Gods great goodneſs to mankind, &c. Some by the light of Gods cloud, here underſtand the Sun-ſhine through the clouds, cauſing it to clear up. Now who can certainly foretel rain or fair weather? Some Learned men have ſpent much time and pains in Aſtronomy to get skill in prognoſticating, but could do little good of it: when they foretel a faire day, it commonly raineth, and the contrary. The Country mans Prognoſticks, the Shepherds Calender, hold better for moſt part, then the Predictions of theſe Artiſans.
