Did he stay around and fight them? Remember, he became very great. Now, when we understand, let us say, about Abraham's greatness, Abraham was able to put together an army. I want you to think about this. In a way, this is what Isaac inherited. Do you think Isaac could have put together an army? Oh yes, he could have because in his own right, he too was a king just like this Abimelech. But in his humility, he did not take the title at all. So Isaac just picked up and left.
Genesis very clearly says God enriched both Abraham and Isaac. God made them wealthy. In a way, here, we have to be careful because people have ideas about a wealthy person. Even Jesus warned of a wealthy person may find it harder to go through to enter the Kingdom of God than a camel going through the eye of a needle. But Abraham and Isaac are going to be in the Kingdom of God, and that wealth did not hinder them from using it rightly and properly.
