Psalm 105:16-22

When he summoned a famine on the land and broke all supply of bread, he had sent a man ahead of them, Joseph, who was sold as a slave. His feet were hurt with fetters; his neck was put in a collar of iron; until what he had said came to pass, the word of the LORD tested him. The king sent and released him; the ruler of the peoples set him free; he made him lord of his house and ruler of all his possessions, to bind his princes at his pleasure and to teach his elders wisdom.
