How did Moses change Judaism?

Answer 1

Moses changed Judaism by leading the Israelites out of Egypt.

Answer:Moses received the Torah from God (Exodus 24:12), making obligatory what had previously been voluntary customs observed by the Forefathers (Talmud, Yoma 28b).
he freed the isrealites from the wicked pharaoh

Answer 2

While the Torah, its commands and the principles and beliefs of Judaism remain unchanged, Judaism has evolved as circumstances have necessitated. Here are just a few examples:
1) After the end of prophecy (some 2350 years ago), the Tanakh was sealed by a special Sanhedrin (Rabbinical court). It was the same Sanhedrin which placed our prayers in their permanent form (see Talmud, Berakhot 33a).
2) Purim and Hanukkah were instituted after the relevant events.
3) Certain fasts were instituted in connection with the Destruction of the Temple.
4) After the Destruction, the laws of sacrifices were suspended.
5) When circumstances made it impossible, the New Moon was no longer proclaimed by testimony; rather, the fixed calendar was instituted (around 360 CE).
6) The Talmud was put in writing (around 500 CE) when it became too hard to be learned by heart.
7) There are seven formal Rabbinical commands. These are:
Saying the blessings over food (and on various occasions)
Washing one's hands before eating bread
Lighting the Hanukkah-menorah
The Eruv
Saying the Hallel prayer on certain occasions
Lighting the Sabbath candles
Reading the Megillat Esther on Purim.
In addition, there are many Rabbinical decrees, mostly from the Men of the Great Assembly (4th century BCE), as well as later enactments.
The purpose of every one of these is to provide a "fence around the Torah," meaning to shore up something that can benefit from strengthening. An example: not handling electric appliances on the Sabbath, even if they are not connected to any electric socket.

Answer 3

A:If Moses was a real, historical person, he came to realise that he was an Israelite and

therefore helped to lead them out of slavery in Egypt. In time, his achievements were

celebrated by the Jews.

OR

Moses was not a real, historical person, the consensus view of scholars. The Hebrew

people needed a glorious hero and created Moses for the purpose. He became involved in

Judaism because his existence and his role in the history and religion of the Jews came

to be accepted as true.

Jewish answer:

Moses was an Israelite, a great-great grandson of Jacob. He was born 245 years after

the death of Abraham. The time when Moses was born was when the Pharaoh ordered

his people to kill all Jewish male infants because he (Pharaoh) was afraid that the

Israelites would become too strong for him (Exodus ch.1-2). Moses' mother didn't want

him to die. So she made a basket for him and put him in it to float in the Nile reeds. He

was found by the Pharaoh's daughter, who took pity on him (Exodus ch.2) and raised him

as her own son. He was forced to flee after killing a cruel Egyptian taskmaster, and went

to Midian, where he wedded the daughter of Jethro. He eventually achieved the highest

level of prophecy (Deuteronomy ch.34) and was called upon by God (Exodus ch.3). He

brought the Israelites out of Egyptian slavery (Exodus ch.12). He received the Torah

from God (Exodus 24:12) and later recorded it in writing (Deuteronomy 31:24). He went

up on Mount Sinai for 40 days and nights (Deuteronomy ch.9-10) and brought down the

Two Stone Tablets with the Ten Commandments (Exodus 31:18). He brought the

Israelites into the covenant with God (Exodus ch.19 and ch.24), and he oversaw the

building of the Tabernacle (Exodus ch.35-40). He was the humblest of men and the

greatest of prophets (Numbers ch.12).

Short Answer:

Through the simplest possible and historically the most widespread process:

By being born to Hebrew parents in a household aware of its heritage and observant

in its traditions to the extent of their knowledge and the best of their ability.
