Job 5:13

He taketh the wise in their own craftiness.

1. The wisdom of natural men is nothing but craft or wit to do wickedly.

2. Satan makes use of subtle, crafty men, and abuseth their parts for his own purposes.

3. The crafty are full of hopes that their devices will succeed; and full of trouble, because they succeed not.

4. What such plot and devise, they labour to act and effect.

5. Crafty men may devise strongly, but they have not strength sufficient to accomplish their devices.

6. It is a great and wonderful work of God, to disappoint the devices and stop the enterprises of crafty men. (J. Caryl.)
