Behold, this is the joy {l} of his way, and out of the earth shall others grow.

(l) To be planted in another place, where it may grow as it pleases.

Wesley's Notes

8:19 Behold - This is the issue of the flourishing state. This all his joy comes to. And, and c. - Out of the same earth or place shall another tree grow.

Jamieson-Fausset-Brown Bible Commentary

19. Bitter irony. The hypocrite boasts of joy. This then is his "joy" at the last.

and out of the earth-others immediately, who take the place of the man thus punished; not godly men (Mt 3:9). For the place of the weeds is among stones, where the gardener wishes no plants. But, ungodly; a fresh crop of weeds always springs up in the place of those torn up: there is no end of hypocrites on earth [Umbreit].

Matthew Henry's Concise Commentary

8:8-19 Bildad discourses well of hypocrites and evil-doers, and the fatal end of all their hopes and joys. He proves this truth of the destruction of the hopes and joys of hypocrites, by an appeal to former times. Bildad refers to the testimony of the ancients. Those teach best that utter words out of their heart, that speak from an experience of spiritual and divine things. A rush growing in fenny ground, looking very green, but withering in dry weather, represents the hypocrite's profession, which is maintained only in times of prosperity. The spider's web, spun with great skill, but easily swept away, represents a man's pretensions to religion when without the grace of God in his heart. A formal professor flatters himself in his own eyes, doubts not of his salvation, is secure, and cheats the world with his vain confidences. The flourishing of the tree, planted in the garden, striking root to the rock, yet after a time cut down and thrown aside, represents wicked men, when most firmly established, suddenly thrown down and forgotten. This doctrine of the vanity of a hypocrite's confidence, or the prosperity of a wicked man, is sound; but it was not applicable to the case of Job, if confined to the present world.
