12 Then Isaac sowed in that land, and reaped in the same year a hundredfold; and the Lord blessed him. 13 The man began to prosper, and continued prospering until he became very prosperous; 14 for he had possessions of flocks and possessions of herds and a great number of servants. So the Philistines envied him. 15 Now the Philistines had stopped up all the wells which his father's servants had dug in the days of Abraham his father, and they had filled them with earth. 16 And Abimelech said to Isaac, "Go away from us, for you are much mightier than we." 17 Then Isaac departed from there and pitched his tent in the Valley of Gerar, and dwelt there.

Commentary on Genesis 26:12-17
(Read Genesis 26:12-17)
God blessed Isaac. Be it 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. It is an instance of the vanity of the world; for the more men have of it, the more they are envied, and exposed to censure and injury. Also of the corruption of nature; for that is an ill principle indeed, which makes men grieve at the good of others. They made Isaac go out of their country. That wisdom which is from above, will teach us to give up our right, and to draw back from contentions. If we are wrongfully driven from one place, the Lord will make room for us in another.
