Verse 20. - And the herdmen of Gerar - i.e. Abimelech's servants (Genesis 21:25) - did strive with Isaac's herdmen, - as Lot's with those of Abraham (Genesis 13:7) - saying, The water is ours: - literally, to us (belong) the waters - and he called the name of the well Esek ("Strife"); because they strove with him - the verb being עָשַׂק, to strive about anything.

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.And the herdmen of Gerar did strive with Isaac's herdmen,.... About the well which was dug in the valley; and this shows it was near Gerar or at least was upon the border of the country, and so it was a disputable point to whom it belonged:

saying, the water is ours; though the well was dug by Isaac's servants, yet they laid claim to the water, pretending it was their ground, being on their borders:

and he called the name of the well Esek: which signifies "contention": the reason of the name follows:

because they strove with him; wrangled, contended, and disputed with him about whose right it was.
