Exodus 1:5-8
Exodus 1:5-8 NIV
The descendants of Jacob numbered seventy in all; Joseph was already in Egypt. Now Joseph and all his brothers and all that generation died, but the Israelites were exceedingly fruitful; they multiplied greatly, increased in numbers and became so numerous that the land was filled with them. Then a new king, to whom Joseph meant nothing, came to power in Egypt.
