'Champion' in the Bible

A champion named Goliath from Gath came out from the Philistine camp. He was four cubits and a span tall,

As he was speaking with them, the Philistine champion named Goliath from Gath came up from the Philistine battle lines and spoke his usual words, as David listened.

David ran and stood over the Philistine. He took the Philistine's sword, pulled it from its sheath, killed him, and then he cut off his head with it. When the Philistines saw that their champion was dead, they fled.

which is like a bridegroom coming out of his chamber, or like a champion who rejoices at the beginning of a race.
