The religion of the Jews is very clear about getting rid of the indigenous population and in fact in Numbers 33:55 of the Jewish Bible, their God tells them that unless they did a complete removal of the indigenous population that God would get angry with them! Take a look:
Numbers 33:55 If you don’t force out all the people there, they will be like pointed sticks in your eyes and thorns in your back. They willalways be trouble for you, 56 and I will treat you as cruelly as I planned on treating them.
