'Adversaries' in the Bible

Our adversaries said, "They shall not know, neither see, until we come into the midst of them, and kill them, and cause the work to cease."

Therefore you delivered them into the hand of their adversaries, who distressed them. In the time of their trouble, when they cried to you, you heard from heaven; and according to your manifold mercies you gave them saviors who saved them out of the hand of their adversaries.
