Moses was born in the 12th dynasty of Egypt. The Israelites were forced to make mud bricks by the pharaohs of this dynasty. Pyramids of the 12th dynasty had an inner core made of mudbricks with a limestone veneer. As limestone was becoming scarce, the Pharaohs were forced to use mudbricks to construct the core of the pyramids of the 12th dynasty and limestone was used only for the outer surface. A large labour force was required to make mud bricks. The Jews had grown to number over 2 million by the 12th dynasty. They were housed in Kahun – a semetic workers village close to Lahun, Dashur and Hawara where the 12th dynasty mud brick pyramids can be found. Petri excavated Kahun in 1889 and found evidence that it was occupied from the early 12th dynasty to the 13th dynasty by foreign Semetic slaves. Scarabs with the names of pharaohs that were found in the town indicate that it was built during the time of Sesostris II and occupied up until the 13th dynasty. Amenemhet III, the son of Sesostris III is most likely the Pharaoh who ordered that the Hebrew children be killed at birth by the midwives. Sobeknefru, his daughter appears to have adopted Moses after finding him amongst the reeds of the Nile in a basket. Moses would have become the next Pharaoh (Amenemhet IV). Moses may have even co-reigned with Amenemhet III for 9 years before he had to flee to Midian after killing an Egptian. Sobekneferu became the Pharaoh when Amenemhet died. Sobeknefru reigned almost 4 yrs before she died and so ended the 12th dynasty. A number of pharaohs followed in quick succession until Neferhotep in the 13th dynasty. Neferhotep was the Pharaoh who Moses confronted when he returned to Egypt 40 yrs after fleeing to Midian. Moses then lead the Israelites (numbering around 2 million) out of Egypt, thru the Red Sea into Arabia where they received the Law at Mt Sinai (Jabel Laws).
