'Foes' in the Bible

You give me strength for battle; you make my foes kneel before me.

So Gad went to David, told him the choices, and asked him, “Do you want three years of famine to come on your land, to flee from your foes three months while they pursue you, or to have a plague in your land three days? Now, think it over and decide what answer I should take back to the One who sent me.”
