John Trapp on Job 29:19

Verſe 19. My root was ſpread out by the waters] Heb. Opened to the waters; which therefore had free recourſe to it, and much refreſhed it. Hereby he deſcribeth his flouriſhing condition when time was, through the perpetual inflowings of Gods free Grace and favour.

And the dew lay all night upon my branch] Pernectabat; becauſe in the night the dew falleth. Beza thus Paraphraſeth this whole verſe: For, downward the root of my good and upright conſcience was ſpred out by the everflowing waters of Gods bountifulneſs, with which it was daily watered: and upward, the boughs growing out of this root, to wit, my children, my ſervants, my flocks of ſheep, and in a word, my ſubſtance, were waſhed with the coeleſtial dew which from heaven fell down upon them: ſo that by this bleſſing of God they were marvellouſly increaſed.
