Power of Faith in Life after Death
It is said that Moses lived around 1300 to 1500 BCE, while the Book of the Dead, an ancient Egyptian funerary text, was written from the beginning of the New Kingdom (around 1550 BCE) to around 50 BCE. Some of the spells included in the book were drawn from these older works and date to the 3rd millennium BCE. (https://en.wikipedia.org/wiki/Book_of_the_Dead).So, there is no wonder that some influence from the Egyptian Book of the Dead is found in the Ten Commandments Moses introduced as given by the God.
According to the Book of the Dead, a dead man must stand before a god to testify as follows to be admitted into life after death:
He never hurt any man,
He never had bad friends,
He never committed harmful acts,
He never inflicted suffering to others,
He never killed anybody,
He never produced injury to anybody,
He was never guilty of adultery,
He never scammed others to get an estate,
He never broke a bank,
He never stole livestock,
He never hated a god,
He never rejected mercy of a god, etc.
Ancient Egyptians who built great pyramids believed life after death. They believed that a god moved across the sky with the sun. So, they must have built great pyramids for their souls after death to ascend to the sky and meet the god. This belief of theirs is symbolized by those great pyramids. The pyramids were built not to appeal to modern tourists but as tools for accessing their god traversing the sky based on their belief in life after death. So, what we should see in those pyramids is their faith in life after death that must have influenced Moses. Indeed, Moses must have learnt that gods loved justice and required men to prove that they were righteous so as to be admitted into the sprit world. On this notion, Judaism was built and Christianity was developed.
Even Abraham is said to have once lived in Egypt:
There was a severe famine in the land of Canaan, so that Abram and Lot and their households traveled to Egypt. On the way Abram told Sarai to say that she was his sister, so that the Egyptians would not kill him. When they entered Egypt, the Pharaoh's officials praised Sarai's beauty to Pharaoh, and they took her into the palace and gave Abram goods in exchange. God afflicted Pharaoh and his household with plagues, which led Pharaoh to try to find out what was wrong. Upon discovering that Sarai was a married woman, Pharaoh demanded that Abram and Sarai leave. (https://en.wikipedia.org/wiki/Abraham)
Even Christ Jesus traveled to Egypt with His parents when He was infant, which is the only account of His trip to abroad.
Herod initiated the Massacre of the Innocents in hopes of killing the child (Matthew 2:16–Matthew 2:18). But an angel appeared to Joseph in a dream and warned him to take Jesus and his mother into Egypt (Matthew 2:13). (https://en.wikipedia.org/wiki/Flight_into_Egypt#Prophecy_of_Hosea)
When Abraham, Moses, and even Christ Jesus and His parents traveled to Egypt, there were already the Three Great Pyramids, including the the Pyramid of Khufu. Therefore, it is natural to think that they must have been heard why those pyramids had been built. They must have confirmed power of faith in the God and life after death.
The history since Abraham must be built on this notion of power of faith in life after death.

Matthew 5, King James Version
16 Let your light so shine before men, that they may see your good works, and glorify your Father which is in heaven.
17 Think not that I am come to destroy the law, or the prophets: I am not come to destroy, but to fulfil.
18 For verily I say unto you, Till heaven and earth pass, one jot or one tittle shall in no wise pass from the law, till all be fulfilled.
19 Whosoever therefore shall break one of these least commandments, and shall teach men so, he shall be called the least in the kingdom of heaven: but whosoever shall do and teach them, the same shall be called great in the kingdom of heaven.
