Charles H. Spurgeon on Psalms 105:22

To bind his princes at his pleasure. He who was bound obtains authority to bind. He is no longer kept in prison, but keeps all the prisons, and casts into them the greatest nobles when justice demands it. And teach his senators wisdom. The heads of the various peoples, the elders of the nations, learned from him the science of government, the art of providing for the people. Joseph was a great instructor in political economy, and we doubt not that he mingled with it the purest morals, the most upright jurisprudence, and something of that divine wisdom without which the most able senators remain in darkness. The king's authority made him absolute both in the executive and in the legislative courts, and the Lord instructed him to use his power with discretion. What responsibilities and honours loaded the man who had been rejected by his brothers, and sold for twenty pieces of silver! What glories crown the head of that greater one who was "separated from his brethren."
