Deuteronomy 7:1 When the Lord thy God shall bring thee into the land, and hath cast out many nations before thee, 2 Thou shalt make no covenant with them. 3 Neither shalt thou make marriages with them; thy daughter thou shalt not give unto his son, nor his daughter shalt thou take unto thy son. 4 For they will turn away thy son from following me, that they may serve other gods: so will the anger of the Lord be kindled against you, and destroy thee suddenly.
[Patriarchs & Prophets pp 332>333] The children of Jacob were tempted to contract marriages with the heathen and to worship their idols. But Joseph was faithful to God, and his fidelity was a constant testimony to the true faith. It was to quench this light that Satan worked through the envy of Joseph's brothers to cause him to be sold as a slave in a heathen land. God overruled events, however, so that the knowledge of Himself should be given to the people of Egypt. Both in the house of Potiphar and in the prison Joseph received an education and training that, with the fear of God, prepared him for his high position as prime minister of the nation.
From the palace of the Pharaohs his influence was felt throughout the land, and the knowledge of God spread far and wide. The Israelites in Egypt also became prosperous and wealthy, and such as were true to God exerted a widespread influence. The idolatrous priests were filled with alarm as they saw the new religion finding favor. Inspired by Satan with his own enmity toward the God of heaven, they set themselves to quench the light. To the priests was committed the education of the heir to the throne, and it was this spirit of determined opposition to God and zeal for idolatry that molded the character of the future monarch, and led to cruelty and oppression toward the Hebrews.
During the forty years after the flight of Moses from Egypt, idolatry seemed to have conquered. Year by year the hopes of the Israelites grew fainter. Both king and people exulted in their power, and mocked the God of Israel. This grew until it culminated in the Pharaoh who was confronted by Moses. When the Hebrew leader came before the king with a message from “Jehovah, God of Israel,” it was not ignorance of the true God, but defiance of His power, that prompted the answer, “Who is Jehovah, that I should obey His voice? ... I know not Jehovah.” From first to last, Pharaoh's opposition to the divine command was not the result of ignorance, but of hatred and defiance.
1st Peter 2:9 But ye are a chosen generation, a royal priesthood, an holy nation, a peculiar people; that ye should shew forth the praises of him who hath called you out of darkness into his marvelous light.
May God add His blessing to the study of His word. "Good night" and God bless!
