8 And there riseth a new king over Egypt, who hath not known Joseph,

10 give help! let us act wisely concerning it, lest it multiply, and it hath come to pass, when war happeneth, that it hath been joined, even it, unto those hating us, and hath fought against us, and hath gone out up of the land.`
