19 And Isaac's servants digged in the valley, and found there a well of springing water.
20 And the herdmen of Gerar did strive with Isaac's herdmen, saying, The water is ours: and he called the name of the well Esek; because they strove with him.
21 And they digged another well, and strove for that also: and he called the name of it Sitnah.
