What does 1 Samuel 17:25 mean?

Some of the men were saying, 'Have you seen this guy coming out to challenge us? He’s here to insult Israel. The king will give a huge reward to whoever kills him. He’ll even let that man marry his daughter and make his whole family exempt from taxes.' 1 Samuel 17:25 - Modern Text Bible

(The soldiers talk about the king’s offer, which shows how desperate Saul is to find someone brave enough to fight Goliath.)
