Charles H. Spurgeon on Psalms 105:20

The king sent and loosed him. He was thrust into the roundhouse by an officer, but he was released by the monarch himself. Even the ruler of the people, and let him go free. The tide had turned, so that Egypt's haughty potentate gave him a call from the prison to the palace. He had interpreted the dreams of captives, himself a captive; he must now interpret for a ruler and become a ruler himself. When God means to enlarge his prisoners, kings become his turnkeys.
