'Warfare' in the Bible

Moreover, Hushai said, “You know your father and his men, that they are mighty men and they are fierce, like a bear robbed of her cubs in the field. And your father is an expert in warfare, and will not spend the night with the people.

“Speak kindly to Jerusalem;And call out to her, that her warfare has ended,That her iniquity has been removed,That she has received of the Lord’s handDouble for all her sins.”
