'Adversaries' in the Bible

Had I not feared the provocation by the enemy,That their adversaries would misjudge,That they would say, “Our hand is triumphant,And the Lord has not done all this.”’

If I sharpen My flashing sword,And My hand takes hold on justice,I will render vengeance on My adversaries,And I will repay those who hate Me.

“Rejoice, O nations, with His people;For He will avenge the blood of His servants,And will render vengeance on His adversaries,And will atone for His land and His people.”

And this regarding Judah; so he said,“Hear, O Lord, the voice of Judah,And bring him to his people.With his hands he contended for them,And may You be a help against his adversaries.”
