Exodus 1 begins by saying the children of Israel continued to increase after the death of Joseph and his brothers and they filled the land of Goshen. By that time there was a new Pharaoh in Egypt that did not know Joseph. The Hebrew word for “know” in Exodus 1:8 is yada. It has a wide variety of meanings but here it more likely means “acknowledge.” This man obviously knew who Joseph was. He just had no regard for Joseph or the laws he had decreed. The Targum Onkelos is an Aramaic version of the Hebrew Bible compiled from the Second Temple period to the Middle Ages. It confirms this idea by saying, “But a new king arose over Mizraim who did not hold valid (or confirm) the decree of Joseph.” 
There was obviously something that happened between the time of Jacob’s death and the time when this new Pharaoh arose in Egypt that caused the Egyptians to fear the strength of the children of Israel. The Targum Onkelos also indicates that this fear was that the Israelites would join their enemies, completely destroy all of the Egyptians, and leave the land. To keep this from happening, the Egyptians forced the Hebrews into harsh slavery.
The Targum Onkelos also explains that Pharaoh had a dream of a balance scale with Egypt (Mizraim) on one side which was outweighed by a lamb on the other side. Two chief magicians named Jannes and Jambres interpreted Pharaoh’s dream to mean that a child would be born to the congregation of Israel that would destroy all of Egypt. For this reason, Pharaoh told the Hebrew (Jehudith) midwives to kill any Hebrew male children when they were born.
The Targum Onkelos also tells us that Shiphrah was Jochebed and Puah was Miriam. Since these women feared God and did not obey Pharaoh’s command, he commanded the male babies to be thrown into the river.
Exodus 2 continues by telling us a man of the house of Levi married a daughter of Levi and had a son who was eventually named Moses. If Moses had an older sister named Miriam and an older brother named Aaron, when would they have been born? The Targum explains that Amram had previously put his elderly wife, Jochebed away on account of Pharaoh’s decree but that he returned to his marriage relationship with her at this time. Obviously, Miriam and Aaron were born prior to Amram putting his wife away.
Miraculously, once they were reunited, a male child was conceived and later born. He was hidden three months but it eventually became necessary to obey Pharaoh’s command and put him in the river—but he was put in an ark or basket that had been sealed with tar and pitch (bitumen) so that it would not leak but float.
As we consider this historical account, isn’t it interesting to realize how numerous children died in the river just like many people died in the flood that covered the whole earth during the time of Noah? At the same time, God in His mercy and grace allowed this child to survive in an ark that was miniature in size compared to the one built by Noah.
Many years later, another child – one of Noah’s descendants would die for the sins of the world; however, at this point in time, the baby in the little ark would be a type of Jesus (Yeshua), the Promised One to come.
Miracle upon miracles, this baby who was hidden for three months was found by Pharaoh’s daughter, lifted up out of the water, and saved from certain death. It is awesome to realize that the Son of Man was also lifted up onto a cross, His dead body was hidden in the grave for three days, and it was raised up from the dead so that anyone who desires can experience God’s mercy and grace and escape eternal death if they choose His way instead of their own.
Time is running out. The pattern of the Exodus may have already begun in our time. You must decide to stay in Babylon the Great or come out of her. What will you do?
