Genesis 44:5 - Joseph Benson’s Commentary on the Old and New Testaments

Whereby indeed he divineth The original word may be rendered, For which he would search thoroughly, or, Concerning which he would certainly divine, or make trial and discovery. As if he had said, Did you think that you could deceive my master? Did you not know that he could divine and discover secret things, whence he hath both his name and preferment? And this cup being much prized and used by him, you might easily think that he would use his art to recover it. You have done evil Very evil, have acted unjustly, unthankfully, and foolishly in so doing.
