When the Israelites had been slaves in Egypt for many years, Jehovah sent Moses and his brother, Aaron, to Pharaoh to ask him to liberate His people.
Kala itu, bangsa Israel menjadi budak di Mesir selama bertahun - tahun. Kemudian, Yehuwa mengutus Musa dan Harun, kakaknya, kepada Firaun untuk meminta agar ia membebaskan umat Allah.
