Matthew Henry Commentary Genesis 26:12-17

"And Isaac sowed in that land, and found in the same year a hundredfold. And Jehovah blessed him. And the man waxed great, and grew more and more until he became very great. And he had possessions of flocks, and possessions of herds, and a great household. And the Philistines envied him. Now all the wells which his father`s servants had digged in the days of Abraham his father, the Philistines had stopped, and filled with earth. And Abimelech said unto Isaac, Go from us. For thou art much mightier than we. And Isaac departed thence, and encamped in the valley of Gerar, and dwelt there." — Genesis 26:12-17 (ASV)

God blessed Isaac. It should be observed, for the encouragement of poor tenants who occupy other people's lands and are honest and industrious, that God blessed him with a great increase.

The Philistines envied Isaac. This is an example of the vanity of the world, for the more people have of it, the more they are envied and exposed to censure and injury. It is also an example of the corruption of nature, for that is an evil principle indeed which makes people grieve at the good of others.

They made Isaac leave their country. The wisdom that comes from above will teach us to give up our right and to withdraw from conflicts. If we are wrongfully driven from one place, the Lord will make room for us in another.
