The Great Deliverer.--The lamb of the Passover symbolized the Lamb of God, the universal Deliverer, and Moses, who led the Lord's people out of Egypt, was also a type of the world's Redeemer. Jesus, whose mission the career of Moses foreshadowed, is repeatedly described in the sacred writings as "like unto Moses;" and Moses, the type of Christ, was reputedly "the meekest of men." How Moses Obtained the Priesthood.--Moses was of the tribe of Levi, and son-in-law to Jethro, from whom he received the Priesthood. "And Jethro received it under the hand of Caleb; "And Caleb received it under the hand of Elihu; "And Elihu under the hand of Jeremy; "And Jeremy under the hand of Gad; "And Gad under the hand of Esaias; "And Esaias also lived in the days of Abraham, and was blessed of him-- "Which Abraham received the Priesthood from Melchizedek, who received it through the lineage of his fathers, even till Noah; "And from Noah till Enoch, through the lineage of their fathers; "And from Enoch to Abel, who was slain by the conspiracy of his brother, who received the Priesthood by the commandments of God, by the hand of his father Adam, who was the first man."--(D. and C. 84:7-16.) Jethro, Priest of Midian.--An account of the relations between Moses and his father-in-law, Jethro the Midianite, may be found in the second, third and eighteenth chapters of Exodus. The Midianites were descendants of Ishmael, son of Abraham. The Call of Aaron.--Moses, having received the Melchizedek Priesthood, organized, by divine direction, the Lesser Priesthood, with Aaron, his brother, at its head. It was in the wilderness of Sinai, fourteen hundred and ninety-one years before the coming of the Savior. The children of Israel, in their exodus from Egypt, after the miraculous passage of the Red Sea, whose retiring waters had rolled over the heads of their enemies, were encamped at the foot of the famous eminence, ever since a sacred way-mark in the history of the Hebrew nation. The Lord came down upon Mount Sinai, "in the sight of all the people," and from the midst of thunders, lightnings and thick clouds, which caused the mountain to quake and obscured his glorious presence from the gaze of the unsanctified multitude, he summoned Moses up into the top of the Mount, and delivered unto him, among other charges, the following: "Take thou unto thee Aaron thy brother, and his sons with him, from among the children of Israel, that he may minister unto me in the priest's office, even Aaron, Nadab and Abihu, Eleazer and Ithamar, Aaron's sons. "And thou shalt make holy garments for Aaron thy brother, for glory and for beauty. "And thou shalt put them upon Aaron thy brother, and his sons with him; and shalt anoint them, and consecrate them, and sanctify them, that they may minister unto me in the priest's office."--(Exodus 28:1-3.)
