40 Now the sojourning of the children of Israel, who dwelt in Egypt, was four hundred and thirty years.

41 And it came to pass at the end of the four hundred and thirty years, even the selfsame day it came to pass, that all the hosts of the Lord went out from the land of Egypt.

42 It is a night to be much observed unto the Lord for bringing them out from the land of Egypt: this is that night of the Lord to be observed of all the children of Israel in their generations.

In these verses we learn that the Israelites lived in Egypt for a total of 430 years. Of course, not all of that time was spent in servitude. There is an unspecific gap of time between when Jacob and his sons came into the land and when a later Pharaoh decided to subjugate the Israelite people. It seems likely that most of their time was spent in freedom, as they were not put under Egyptian oppression until they had grown to a mighty number, and the population growth would have started relatively slowly, becoming exponentially greater with each passing generation.

430 years was long enough to make all the stories of Abraham, Isaac, and Jacob, the great patriarchs, distant history to the current generation. Consider that 430 years before today’s date would have been 1593, which was the time period of William Shakespeare and Galileo Galilei. Shakespeare is as far removed to us as Jacob was to Moses. Not completely removed, still well known and with a clear line of connection in between, but removed still the same.

Thus, it was a new Israelite nation that emerged from Egypt, far different from the one that went in. This new Israelite nation was one that knew nothing of its forefathers’ land of inheritance. It was one that had become accustomed to living under another’s rule. It was one that had been surrounded by all manner of false gods and strange practices. But in spite of all this they were being called to reconnect with their foreordained place in the world.
