Job 8:6

If thou wert pure and upright. — Of course, then, there is but one inference: thou art not pure and upright. These are verily the wounds of a friend which are not faithful. Bildad brings to the maintenance of his point the experience of former generations. He wishes to be very orthodox in his assertions, and to base his statements upon authority, and he appeals to the experience of former ages long gone by, and calls them to attest the truth of what he says. He also, like Eliphaz, uses figures, and has recourse to metaphor, only his figures are highly obscure and admit of various explanations. We give that which seems to commend itself most to us. It appears, then, that Bildad contemplates two representative characters, the two which are so prominent throughout this book — namely, the righteous and the wicked. He depicts the latter first, and describes him under the likeness of the paper-reed, or rush that grows in the mire of Egyptian swamps, which, though surrounded with moisture, yet as a matter of fact is liable soon to wither: so is the wicked man, according to this moralist and philosopher. He is surrounded by mercies and blessings, but they avail him nought; he withereth in the midst of abundance.
