Matthew Poole and continuators on Job 23:14

14. For he performeth the thing that is appointed for me : and many such things are with him .

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.

There are many such examples of Gods proceeding with men in way of absolute Soveraignty 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.
