'Adversaries' in the Bible

These Israelites took away their livestock: their 50,000 camels, and 250,000 sheep, and 2,000 donkeys; and 100,000 people.

David went out to meet them and said to them, “If you have come peacefully to me to help me, my heart shall be united with you; but if you have come to betray me to my adversaries, since there is no violence or wrong in my hands, may the God of our fathers look on [what you are doing] and punish [you].”
