'Foe' in the Bible

Edom will be a conquered nation and Seir will be Israel's defeated foe, while Israel performs valiantly.

Out of the mouths of infants and nursing babies you have established strength on account of your adversaries, in order to silence the enemy and vengeful foe.

He delivered them from the power of their foe; redeeming them from the power of their enemy.

All your lovers have forgotten you; they don't seek you. Indeed, I've struck you down with the blow of an enemy, with the punishment of a cruel foe because your wickedness is great, and your sins are numerous.
