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.

Then Isaac sowed in that land—During his sojourn in that district he farmed a piece of land, which, by the blessing of God on his skill and industry, was very productive (Isa 65:13; Ps 37:19); and by his plentiful returns he increased so rapidly in wealth and influence that the Philistines, afraid or envious of his prosperity, obliged him to leave the place (Pr 27:4; Ec 4:4). This may receive illustration from the fact that many Syrian shepherds at this day settle for a year or two in a place, rent some ground, in the produce of which they trade with the neighboring market, till the owners, through jealousy of their growing substance, refuse to renew their lease and compel them to remove elsewhere.
