Job 10:13

And these things hast thou hid in thine heart - Thou hast had many gracious purposes concerning me which thou hast not made known; but thy visitations and mercy are sufficient proofs of kindness towards me; though for purposes unknown to me thou hast sorely afflicted me, and continuest to treat me as an enemy.

And these things hast thou hid in thine heart - This may either refer to the arrangements by which God had made him, or to the calamities which he had brought upon him. Most expositors suppose that the latter is intended. Such is the opinion of Rosenmuller, Good, Noyes, and Scott. According to this the idea is, that God had purposed in his heart to bring these calamities upon him. They were a part of his counsel and design. To hide in the heart, or to lay up in the heart, is a phrase expressive of a secret purpose. I see no reason to confine it, however, to the calamities which Job had experienced. It may refer to all the plans and doings of the Most High, to which Job had just referred. All his acts in the creation and preservation of man, were a part of his secret counsel, He had formed the plan in his heart, and was now executing it in the various dispensations of his providence.

I know that this is with thee - That all this is a part of thy purpose. It has its origin in thee, and is according to thy counsel. This is the language of piety, recognizing the great truth that all things are in accordance with the purposes of God, or that his plans embrace all events - a doctrine which Job most assuredly held.

10:13 Hid - Both thy former favours and thy present frowns. Both are according to thy own will, and therefore undoubtedly consistent, however they seem. When God does what we cannot account for, we are bound to believe, there are good reasons for it hid in his heart. It is not with us, or in our reach to assign the cause; but I know this is with thee.
