'Defy' in the Bible

Then the Philistine said, "I defy Israel's troops this day! Give me a man so we can fight each other!"

The men of Israel said, "Have you seen this man who is coming up? He does so to defy Israel. But the king will make the man who can strike him down very wealthy! He will give him his daughter in marriage, and he will make his father's house exempt from tax obligations in Israel."
