'Champion' in the Bible

Why should you be like someone who is helpless, like a champion who cannot save anyone? You are indeed with us, and we belong to you. Do not abandon us!"

But the Lord is with me like a dread champion;Therefore my persecutors will stumble and not prevail.They will be utterly ashamed, because they have failed,With an everlasting disgrace that will not be forgotten.

But the one who will rescue them is strong. He is known as the Lord who rules over all. He will strongly champion their cause. As a result he will bring peace and rest to the earth, but trouble and turmoil to the people who inhabit Babylonia.
