Genesis 26:19-21

19But when Isaac’s servants dug in the valley and found there a well of spring water, 20the herdsmen of Gerar aquarreled with Isaac’s herdsmen, saying, “The water is ours.” So he called the name of the well Esek,
 Esek means contention
because they contended with him.
21Then they dug another well, and they quarreled over that also, so he called its name Sitnah.
 Sitnah means enmity

Judges 1:15

15She said to him, “Give me a blessing. Since you have set me in the land of the Negeb, give me also springs of water.” And Caleb gave her the upper springs and the lower springs.
