Job 5:9 - Matthew Poole's English Annotations on the Holy Bible

Here Eliphaz enters upon a discourse of the infinite perfection and greatness of God's nature and works; which he doth partly as an argument to enforce the exhortation to seek and commit his cause to God, Job 5:8, because God was infinitely able, either to punish him yet far worse, if he continued to provoke him, or to raise him from the dust, if he humbly addressed himself to him; and partly that by a true representation of God's excellency and glory, and of that vast disproportion which was between God and Job, he might both convince Job of his great sin in speaking so boldly and irreverently of him, and prevent his relapse into the same miscarriage. Unsearchable; either such things as we may not boldly and curiously search into, Deuteronomy 29:29 Romans 11:33 Colossians 2:18; or such as by searching we cannot find out, Job 11:7; such as we cannot thoroughly understand, either the works themselves, or God's way and manner of doing them, or God's designs or ends in doing them. And therefore, O Job, thou art guilty of great impiety and folly to censure the ways and works of God as unreasonable, Job 3:11,20, because thou dost not fully understand the nature and use of them. Marvellous things; which (though common, as the following works are, and therefore neglected and despised, yet) are just matter of wonder even to the wisest men.
