Genesis 26:18

18. And Isaac digged again the wells of water. First, we see that the holy man was so hated by his neighbors, as to be under the necessity of seeking a retreat for himself which was destitute of water; and no habitation is so troublesome and inconvenient for the ordinary purposes of life as that which suffers from scarcity of water. Besides, the abundance of his cattle and the multitude of his servants — who were like a little army — rendered a supply of water very necessary; whence we learn that he was brought into severe straits. But that this last necessity did not instigate him to seek revenge, is a proof of singular forbearance; for we know that lighter injuries will often rack the patience even of humane and moderate men. If any one should object to this view, that he was deficient in strength; I grant, indeed, that he was not able to undertake a regular war; but as his father Abraham had armed four hundred servants, he also certainly had a large troop of domestics, who could easily have repelled any force brought against him by his neighbors. But the hope which he had entertained when he settled in the valley of Gerar, was again suddenly cut off. He knew that his father Abraham had there used wells which were his own, and which he had himself discovered; and although they had been stopped up, yet they were well known to have sufficient springs of water to prevent the labor of digging them again from being misspent. Moreover, the fact that the wells had been obstructed ever since the departure of Abraham, shows how little respect the inhabitants had for their guest; for although their own country would have been benefited by these wells, they chose rather to deprive themselves of this advantage than to have Abraham for a neighbor; for, in order that such a convenience might not attract him to the place, they, by stopping up the wells, did, in a certain sense, intercept his way. It was a custom among the ancients, if they wished to involve any one in ruin, and to cut him off from the society of men, to interdict him from water, and from fire: thus the Philistine, for the purpose of removing Abraham from their vicinity, deprive him of the element of water.

He called their names. He did not give new names to the wells, but restored those which had been assigned them by his father Abraham, that, by this memorial, the ancient possession of them might be renewed. But subsequent violence compelled him to change their names, that at least he might, by some monument, make manifest the injury which had been done by the Philistines, and reprove them on account of it: for whereas he calls one well strife, or contention, another hostility, he denies that the inhabitants possessed that by right, or by any honest title, which they had seized upon as enemies or robbers. Meanwhile, it is right to consider, that in the midst of these strifes he had a contest not less severe with thirst and deficiency of water, whereby the Philistines attempted to destroy him; such is the scope of the history. First, Moses, according to his manner, briefly runs through the summary of the affair: namely, that Isaac intended to apply again to his own purpose the wells which his father had previously found, and to acquire, in the way of recovery, the lost possession of them. He then prosecutes the subject more diffusely, stating that, when he attempted the work, he was unjustly defrauded of his labor; and whereas, in digging the third well, he gives thanks to God, and calls it Room, because, by the favor of God, a more copious supply is now afforded him, he furnishes an example of invincible patience. Therefore, however severely he may have been harassed, yet when, after he had been freed from these troubles, he so placidly returns thanks to God, and celebrates his goodness, he shows that in the midst of trials he has retained a composed and tranquil mind.
