Judaism probably begins in the book of Exodus 19:3.
Although it may begin when the Lord changes Abram’s name to Abraham and establishes his covenant between Abraham and his descendants, Genesis 17:1-8.
Note Abram called a Hebrew in Genesis 14:13 (KJV) “Abram the Hebrew” Let us start with the 10th plagues where all the firstborn in the land of Egypt shall die, from the firstborn of Pharaoh that sitteth upon his throne, even unto the firstborn of the Children of Israel, and all the firstborn of beasts.
The 10th plagues take the life of the Pharaoh of Egypt’s firstborn son, but the firstborn of the Children of Israel are spared because They took the blood of a lamb and struck it on the two side posts and on the upper door post of their houses, and when the Lord seeth the blood upon the lintel, and on the two side posts, he will pass over the door, and will not suffer the destroyer to come in unto your houses to smite you.
With the destroyer passing over the obeyed Children of Israel, the plague shall not be upon them to destroy when I smite the land of Egypt taking the firstborn. This day shall be unto you for a memorial, called the Passover, it is the sacrifice of the LORD’S Passover, who passed over the houses of the children of Israel in Egypt, when he smote the Egyptians and delivered our houses.
the Lord hardened Pharaoh’s heart who sends his army after the Children of Israel, but The Lord leads the people through the way of the wilderness of the Red sea. The LORD goes before them by day in a pillar of a cloud, to lead them the way, and by night in a pillar of fire, to give them light. They are protected to travel by day and night.
Pharaoh’s army is kept from seeing the Children of Israel by the cloud. When the Children of Israel reach the Red Sea Moses raises his hand and the waters part allowing the children of Israel to walk on dry land through the parted waters, Exodus 14:21.
After the children of Israel are safely on the far side of the Red Sea, Moses raises his hand and the cloud is lifted in front of the Pharaoh’s army and In hot pursuit, They see the parted waters and follow through. Once the army on their horse-drawn chariots is entirely on the sea bed Moses raises his hand and the waters close over them and they perish, Exodus 14:23-27.
The Pharaoh minus his army is never heard from again. After rejoicing the Israelites journey through the wilderness for three months and arrive at the base of Mount Sinai and camp.
Note, But Moses said, “The people, among whom I am, are 600,000 on foot;” Numbers 11:21. Moses goes up on Mount Sinai and speaks to the Lord, Exodus 19:3-8.
And Moses went up unto God, and the LORD called unto him out of the mountain, saying, Thus shalt thou say to the house of Jacob, and tell the children of Israel, Ye have seen what I did unto the Egyptians, and how I bare you on eagles’ wings and brought you unto myself.
Now, therefore, if ye will obey my voice indeed, and keep my covenant, then ye shall be a peculiar treasure unto me above all people: for all the earth is mine.
And ye shall be unto me a kingdom of priests, and an holy nation. These are the words which thou shalt speak unto the children of Israel.
And Moses came and called for the elders of the people, and laid before their faces all these words which the LORD commanded him.
And all the people answered together, and said, All that the LORD hath spoken we will do. And Moses returned the words of the people unto the LORD.
In Exodus 20:, 23:19 the Lord gives extensive commandments and ordinances to the children of Israel. On Mount Sinai the LORD speaks to Moses, saying, Tell the sons of Israel to raise a contribution for him and explain what he wants the Tabernacle to be made of.
This is the contribution which they are to raise, Exodus 25:3-9. gold, silver, and bronze, blue, purple, and scarlet material, fine linen, goat hair, rams’ skins dyed red, porpoise skins, acacia wood, oil for lighting, spices for the anointing oil and for the fragrant incense, onyx stones, and setting stones, for the ephod and for the breastpiece.
And let them construct a sanctuary for Me, that I may dwell among them. According to all that I am going to show you, as the pattern of the tabernacle and the pattern of all its furniture, just so you shall construct it.
In Exodus 25:10-21, some are given how the Ark of the Covenant should be constructed. The Ark of the Covenant is a beautiful and elaborate coffer that was to be carried about.
there was to be an altar used for offerings, and behind a veil was to contain the Ark of the Covenant or (testimony) and the proposed veil divided the congregation between the holy place and the most holy.
In Exodus 25:16, Inside the Ark was to be placed the testimony which the Lord had given Moses the two tablets of stone.
And we see in Exodus 26:34 the ark of the testimony is to be placed in the tabernacle in the most holy place.
In Exodus 31:1-11, those people who were to do the construction were given the talent of craftsmanship in order that the tabernacle might be built with the Exquisite material it was to be made from.
In Exodus 32:15-20, Moses comes down from mount Sinai with two tablets of stone. Note, this is the first time with the two tables of stone.
The two tables of stone are which had been written on both their sides by God. There he saw a golden calf that had been built and worshipped by the Israelites. He casts the tables of stone and they broke beneath the mount. he takes the calf which they had made and burnt it in the fire, and ground it to powder, and strowed it upon the water, and made the children of Israel drink of it.
Because they had turned aside out of the way which the Lord had commanded them and corrupted themselves Moses said unto them, Thus saith the LORD God of Israel, Put every man his sword and The children of Levi did according to the word of Moses: and there slew that day about three thousand men, Exodus 32:26-28.
