10 Come, let’s deal wisely with them. Otherwise they will continue to multiply, and if a war breaks out, they will ally themselves with our enemies and fight against us and leave the country.”

Darby

10 Come on, let us deal wisely with them, lest they multiply, and it come to pass that, if war occur, they take side with our enemies and fight against us, and go up out of the land.

KJV

10 Come on, let us deal wisely with them; lest they multiply, and it come to pass, that, when there falleth out any war, they join also unto our enemies, and fight against us, and [so] get them up out of the land.
