Bildad is the second friend of Iyov,

He also offers accusation rather than support.

In his attempt to justify God, he essentially claims that Iyov's children must have died for their sins; and that Iyov is innocent, he will soon be rewarded. His proofs come from nature.

Interestingly, many of these arguments and metaphors are reflected in various Psalms, but Iyov will not accept these arguments. They do not apply to him; precisely because he is innocent.
