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. 18 And Isaac dug again the wells of water which they had dug in the days of Abraham his father, for the Philistines had stopped them up after the death of Abraham. He called them by the names which his father had called them. 19 Also Isaac's servants dug in the valley, and found a well of running water there. 20 But the herdsmen of Gerar quarreled with Isaac's herdsmen, saying, "The water is ours." So he called the name of the well Esek, because they quarreled with him. 21 Then they dug another well, and they quarreled over that one also. So he called its name Sitnah. 22 And he moved from there and dug another well, and they did not quarrel over it. So he called its name Rehoboth, because he said, "For now the Lord has made room for us, and we shall be fruitful in the 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.
