'Learn' in the Bible

Right about then, a prophet approached King Ahab of Israel and told him, "This is what the LORD says: "You see all of this great big army, do you? Well now, I'm going to deliver them all right into your hand, and you will learn that I am the LORD!'"

Right about then, a man of God approached and told the king of Israel, "This is what the LORD says: "Because the Arameans keep saying "The LORD is a mountain god, but isn't a valley god," I'm going to deliver this entire vast army right into your control, so you'll learn that I really am the LORD.'"
