Genesis 26:19-21 New English Translation (NET)

19. When Isaac’s servants dug in the valley and discovered a well with fresh flowing water there,

20. the herdsmen of Gerar quarreled with Isaac’s herdsmen, saying, “The water belongs to us!” So Isaac named the well Esek because they argued with him about it.

21. His servants dug another well, but they quarreled over it too, so Isaac named it Sitnah.
