<P> Jacob and his sons are forced by famine to go down into Egypt, although Joseph was already there, as he had been sold into slavery while young . When they arrive they and their families are 70 in number, but within four generations they have increased to 600,000 men of fighting age, and the Pharaoh of Egypt, alarmed, first enslaves them and then orders the death of all male Hebrew children . A woman from the tribe of Levi hides her child, places him in a woven basket, and sends him down the Nile river . He is named Mosheh, or Moses, by the Egyptians who find him . Being a Hebrew baby, they award a Hebrew woman the task of raising him, the mother of Moses volunteers, and the child and his mother are reunited . </P> <P> At the age of forty Moses kills an Egyptian, after he sees him beating a Hebrew to death, and escapes as a fugitive into the Sinai desert, where he is taken in by the Midianites and marries Zipporah, the daughter of the Midianite priest Jethro . When he is eighty years old, Moses is tending a herd of sheep in solitude on Mount Sinai when he sees a desert shrub that is burning but is not consumed . The God of Israel calls to Moses from the fire and reveals his name, Yahweh (from the Hebrew root word' HWH' meaning to exist), and tells Moses that he is being sent to Pharaoh to bring the people of Israel out of Egypt . </P> <P> Yahweh tells Moses that if Pharaoh refuses to let the Hebrews go to say to Pharaoh "Thus says Yahweh: Israel is my son, my first - born and I have said to you: Let my son go, that he may serve me, and you have refused to let him go . Behold, I will slay your son, your first - born". Moses returns to Egypt and tells Pharaoh that he must let the Hebrew slaves go free . Pharaoh refuses and Yahweh strikes the Egyptians with a series of horrific plagues, wonders, and catastrophes, after which Pharaoh relents and banishes the Hebrews from Egypt . Moses leads the Israelites out of bondage toward the Red Sea, but Pharaoh changes his mind and arises to massacre the fleeing Hebrews . Pharaoh finds them by the sea shore and attempts to drive them into the ocean with his chariots and drown them . </P> <P> Yahweh causes the Red Sea to part and the Hebrews pass through on dry land into the Sinai . After the Israelites escape from the midst of the sea, Yahweh causes the ocean to close back in on the pursuing Egyptian army, drowning them to death . In the desert Yahweh feeds them with manna that accumulates on the ground with the morning dew . They are led by a column of cloud, which ignites at night and becomes a pillar of fire to illuminate the way, southward through the desert until they come to Mount Sinai . The twelve tribes of Israel encamp around the mountain, and on the third day Mount Sinai begins to smolder, then catches fire, and Yahweh speaks the Ten Commandments from the midst of the fire to all the Israelites, from the top of the mountain . </P>
