The herdsmen of Gerar argued with Isaac's herdsmen, saying, "The water is ours." He called the name of the well Esek, because they contended with him.

And they digged another well, and contended for that also: and he called the name of it Sitnah.

And it was vexing to Jacob and he contended with Laban, - and Jacob responded and said to Laban, What was my trespass, what my sin, that thou shouldst have come burning after me?

Then he said - Not Jacob, shall thy name be called any more, but Israel, - For thou hast contended with God and with men and hast prevailed.

Again God said to him,

“Your name is Jacob;
You shall no longer be called Jacob,
But Israel shall be your name.”

So he was called Israel.
