Genesis 26

17. valley of Gerar--torrent-bed or wady, a vast undulating plain, unoccupied and affording good pasture.

18-22. Isaac digged again the wells of water--The naming of wells by Abraham, and the hereditary right of his family to the property, the change of the names by the Philistines to obliterate the traces of their origin, the restoration of the names by Isaac, and the contests between the respective shepherds to the exclusive possession of the water, are circumstances that occur among the natives in those regions as frequently in the present day as in the time of Isaac.

26-33. Then Abimelech went to him--As there was a lapse of ninety years between the visit of Abraham and of Isaac, the Abimelech and Phichol spoken of must have been different persons' official titles. Here is another proof of the promise ( Genesis 12:2 ) being fulfilled, in an overture of peace being made to him by the king of Gerar. By whatever motive the proposal was dictated--whether fear of his growing power, or regret for the bad usage they had given him, the king and two of his courtiers paid a visit to the tent of Isaac ( Proverbs 16:7 ). His timid and passive temper had submitted to the annoyances of his rude neighbors; but now that they wish to renew the covenant, he evinces deep feeling at their conduct, and astonishment at their assurance, or artifice, in coming near him. Being, however, of a pacific disposition, Isaac forgave their offense, accepted their proposals, and treated them to the banquet by which the ratification of a covenant was usually crowned.

34. Esau . . . took to wife--If the pious feelings of Abraham recoiled from the idea of Isaac forming a matrimonial connection with a Canaanitish woman [ Genesis 24:3 ], that devout patriarch himself would be equally opposed to such a union on the part of his children; and we may easily imagine how much his pious heart was wounded, and the family peace destroyed, when his favorite but wayward son brought no less than two idolatrous wives among them--an additional proof that Esau neither desired the blessing nor dreaded the curse of God. These wives never gained the affections of his parents, and this estrangement was overruled by God for keeping the chosen family aloof from the dangers of heathen influence.
