'Enmity' in the Bible

Thus said the Lord Jehovah: Because of the doings of the Philistines in vengeance, And they take vengeance with despite in soul, To destroy -- the enmity age-during!

Because of thy having an enmity age-during, And thou dost saw the sons of Israel, By the hands of the sword, In the time of their calamity, In the time of the iniquity of the end:

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.
