The prophet's actions are a symbolic metaphor that illustrates the way that Ahab would defeat the Arameans. Ahab's army will win with great strength, as a bull attacks another animal. AT: "With horns like these, your army will keep attacking the army of Aram like a bull attacks another animal, until you completely destroy them" (See: [[rc://en/ta/man/translate/translate-symaction]] and [[rc://en/ta/man/translate/figs-metaphor]])
Here the king's "hand" refers to his control. This means that God will enable them to defeat the people at Ramoth Gilead. AT: "has allowed the king to capture it" or "will allow your armies to capture it" (See: [[rc://en/ta/man/translate/figs-metonymy]] and [[rc://en/ta/man/translate/figs-explicit]])
