Genesis 26:19-21

Amplified Bible

¹⁹ But when Isaac’s servants dug in the valley and found there a well of flowing [spring] water, ²⁰ the herdsmen of Gerar quarreled with Isaac’s herdsmen, saying, “The water is ours!” So Isaac named the well Esek (quarreling), because they quarreled with him. ²¹ Then his servants dug another well, and they quarreled over that also, so Isaac named it Sitnah (enmity).
