Verse 10. - Shall not they teach thee, and tell thee, and utter words out of their heart (see the comment on ver. 8).

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.Shall not they teach thee, and tell thee,.... That is, the men of the former age, and their fathers before them, Job is directed to inquire of, and to prepare for a search into their records and traditions; from whom he might reasonably expect to be taught and told things that would be very instructive and useful to him in his present circumstances:

and utter words out of their heart? such as were the effect of mature judgment and long observation, and which they had laid up in their hearts, and brought out from their treasure there; and, with the greatest faithfulness and sincerity, had either committed them to writing, or delivered them in a traditionary way to their posterity, to be communicated to theirs; and which might be depended upon as true and genuine, being men of probity, uprightness, and singleness of heart; who declared sincerely what they knew, and spoke not with a double heart, having no intention to deceive, as it cannot be thought they would impose upon their own children; and therefore Job might safely receive what they uttered, and depend upon it as truth and fact; and what they said, as Jarchi observes, is as follows; or what follows Bildad collected from them, and so might Job, and think he heard them "saying", as Piscator supplies the text, what is expressed in the following verses, if not in their words, yet as their sense.
