Exodus 1:7 DBY

⁵  And all the souls that had come out of the loins of Jacob were seventy souls; and Joseph was in Egypt.

⁶  And Joseph died, and all his brethren, and all that generation.

⁷  And the children of Israel were fruitful, and swarmed and multiplied, and became exceeding strong; and the land was full of them.

⁸  And there arose a new king over Egypt, who did not know Joseph.

⁹  And he said to his people, Behold, the people of the children of Israel are more numerous and stronger than we.
