Exodus 1:8-10

8 Now a new king came to power in Egypt, who had no knowledge of Joseph.

9 And he said to his people, See, the people of Israel are greater in number and in power than we are:

10 Let us take care for fear that their numbers may become even greater, and if there is a war, they may be joined with those who are against us, and make an attack on us, and go up out of the land.
