Job 36:15

i.e. Causeth them to hear, and understand, and do the will of God; hearing being oft put for obeying. And this latter clause seems to be added, to intimate that he will not deliver all afflicted persons, but only those whose ears he openeth to receive his counsels. In oppression, i.e. in the time of their oppression. Or, by oppression or tribulation, as the means of opening their ears and hearts.
