Job 8:16

"It's wet in the sun. They are corrupted under the flood of human passions. He says, "In the sun," under the weight of tribulation. In front, can mean under; so we say; do it before me, before my eyes. "And by rotting it makes its seed grow. If they had not been so perverted, passion would not have raised him who was born of them according to the flesh (1).

The papyrus and the reed are dried by the scorching heat of the sun and their shoots rot, even though they are moistened by water. In fact, this is what "his branch shall sprout from his dung heap" means. The impious will suffer the same destiny, when the wrath of God falls upon them. Bildad appears to allude to the death of Job's children through his use of "branch," which can indicate shoots, branches or flowers.

It is seen moist before the sun cometh, and his produce issueth forth in his springing up. Oftentimes in Holy Writ the Lord is represented by the title of the Sun, as it is said by the Prophet, But unto you that fear My Name shall the Sun of righteousness arise. And as the ungodly that are cast away in the Judgment, are described in the book of Wisdom, as saying, We have erred from the way of truth, and the light of righteousness hath not shined unto us, and the Sun rose not upon us; therefore, 'before the sun the rush is seen moist,' in that before God's severity burns hot in the Judgment, every hypocrite shews himself bedewed with the grace of holiness. He is seen as it were flourishing, because he is accounted righteous, he wins the post of honour, he is strong in his high repute for sanctity, reverence is awarded to him by all men, his credit for praise is magnified. Thus this rush is full of moisture in the night, but on the coming of the sun it is dried up, in that the hypocrite is accounted holy by all men in the darkness of the present life, but when the searching Judge cometh, he will appear as wicked as he is. So then let him say, He appears moist before the sun, because now he shews himself flourishing to the eyes of men, but then he shall wither up in the scorching heat of the Divine Judgment. For every herb in general is first raised out of the ground by springing up, it is subject to the influences of the air and heat, it is fed by the sun and showers, and then at length it is made to open itself to put forth the produce of its seed. But the rush is produced along with its flower, and so soon as it springs out of the earth, it puts forth its produce of seed with itself. Therefore by the rest of the herbs the Saints in general are well denoted, but the hypocrite by 'the rush,' because the righteous, before they spring up in the practice of holy conversation, undergo the winter season of this life, and the heats of bitter persecutions press them hard; and then, when they do what is right, they never look here for the reward of their, righteousness, but when they depart forth from the labours of the present world, on coming to their eternal Country, they enter upon the enjoyment of their looked-for reward. But contrariwise the hypocrite, in that he springs up in good practice at once, goes about to win the glory of the present world. As it were…
