'Hostile' in the Bible

Then Abner was very angry at the words of Ish-bosheth, and he said, “Am I a dog’s head [a despicable traitor] that belongs to Judah? Today I show loyalty and kindness to the house of Saul your father, to his brothers and his friends, by not having you handed over to David; and yet you charge me today with guilt concerning this woman.

You rescue me from a hostile army; you preserve me as a leader of nations; people over whom I had no authority are now my subjects.
