'Champion' in the Bible

Then a champion came out from the armies of the Philistines named Goliath, from Gath, whose height was six cubits and a span.

As he was talking with them, behold, the champion, the Philistine from Gath named Goliath, was coming up from the army of the Philistines, and he spoke these same words; and David heard them.

Then David ran and stood over the Philistine and took his sword and drew it out of its sheath and killed him, and cut off his head with it. When the Philistines saw that their champion was dead, they fled.

It will become a sign and a witness to the Lord of hosts in the land of Egypt; for they will cry to the Lord because of oppressors, and He will send them a Savior and a Champion, and He will deliver them.

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.
