'Enmity' in the Bible

‘Thus says the Lord God, “Because the Philistines have acted revengefully and have taken vengeance [contemptuously] with malice in their hearts to destroy with everlasting hostility and hatred,”

Because you [descendants of Esau] have had an everlasting hatred [for Jacob (Israel)] and you handed over the sons of Israel to the power of the sword at the time of their tragedy, at the time of their final punishment [the Babylonian conquest],

therefore, as I live,” says the Lord God, “I will deal with you in accordance with the anger and envy you showed because of your hatred for them; and I will make Myself known among them [as Judge] when I judge and punish you.
