'Adversaries' in the Bible

were it not that I feared the provocation of the enemy, lest their adversaries should judge wrongly, lest they should say, 'Our hand is exalted, Yahweh has not done all this.'"

if I whet my glittering sword, My hand take hold on judgment; I will render vengeance to my adversaries, and will recompense those who hate me.

Rejoice, you nations, [with] his people, for he will avenge the blood of his servants. He will render vengeance to his adversaries, And will make expiation for his land, for his people.

This is [the blessing] of Judah: and he said, "Hear, Yahweh, the voice of Judah. Bring him in to his people. With his hands he contended for himself. You shall be a help against his adversaries."
