12 When Isaac planted his crops that year, he harvested a hundred times more grain than he planted, for the Lord blessed him. 13 He became a very rich man, and his wealth continued to grow. 14 He acquired so many flocks of sheep and goats, herds of cattle, and servants that the Philistines became jealous of him. 15 So the Philistines filled up all of Isaac's wells with dirt. These were the wells that had been dug by the servants of his father, Abraham. 16 Finally, Abimelech ordered Isaac to leave the country. "Go somewhere else," he said, "for you have become too powerful for us." 17 So Isaac moved away to the Gerar Valley, where he set up their tents and settled down. 18 He reopened the wells his father had dug, which the Philistines had filled in after Abraham's death. Isaac also restored the names Abraham had given them. 19 Isaac's servants also dug in the Gerar Valley and discovered a well of fresh water. 20 But then the shepherds from Gerar came and claimed the spring. "This is our water," they said, and they argued over it with Isaac's herdsmen. So Isaac named the well Esek (which means "argument"). 21 Isaac's men then dug another well, but again there was a dispute over it. So Isaac named it Sitnah (which means "hostility"). 22 Abandoning that one, Isaac moved on and dug another well. This time there was no dispute over it, so Isaac named the place Rehoboth (which means "open space"), for he said, "At last the Lord has created enough space for us to prosper in this land."

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.

Commentary on Genesis 26:18-25

(Read Genesis 26:18-25)

Isaac met with much opposition in digging wells. Two were called Contention and Hatred. See the nature of worldly things; they make quarrels, and are occasions of strife; and what is often the lot of the most quiet and peaceable; those who avoid striving, yet cannot avoid being striven with. And what a mercy it is to have plenty of water; to have it without striving for it! The more common this mercy is, the more reason to be thankful for it. At length Isaac digged a well, for which they strove not. Those that study to be quiet, seldom fail of being so. When men are false and unkind, still God is faithful and gracious; and his time to show himself so is, when we are most disappointed by men. The same night that Isaac came weary and uneasy to Beer-sheba, God brought comforts to his soul. Those may remove with comfort who are sure of God's presence.
