This lesson covers Acts 7:9-6 and 8:1-3. 7:9 And the patriarchs, moved with envy, sold Joseph into Egypt: but God was with him, 10 And delivered him out of all his afflictions, and gave him favour and wisdom in the sight of Pharaoh king of Egypt; and he made him governor over Egypt and all his house. 11 Now there came a dearth over all the land of Egypt and Chanaan, and great affliction: and our fathers found no sustenance. 12 But when Jacob heard that there was corn in Egypt, he sent out our fathers first.
