Genesis 26:21

And they digged another well
That is, Isaac's servants: and strove for that also;
the herdsmen of Gerar disputed their right to that also, and strove to get it from them: and he called the name of it Sitnah;
which signifies "hatred", it being out of hatred and malice to him that they gave him so much trouble; from this word Satan has his name, and these men were of a diabolical spirit, envious, spiteful, and malicious.
