Exodus 1
7 Ref And the children of Israel were fertile, increasing very greatly in numbers and in power; and the land was full of them.
8 Ref Now a new king came to power in Egypt, who had no knowledge of Joseph.
9 Ref And he said to his people, See, the people of Israel are greater in number and in power than we are:
10 Ref 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.
