Job 23:14 - Matthew Poole's English Annotations on the Holy Bible

Or, he will perfect or finish my appointed portion, i.e. those calamities which he hath allotted to me for my portion, which as he hath begun to lay on me, so he is resolved to make a full end of them. And many such things are with him; there are many such examples of God's proceeding with men in way of absolute sovereignty and severity, and his counsels and providences, though always just, yet are oft secret, and we cannot discern the reasonableness or equity of them, which is my case.
