Explanation:

The tales about "Sir Gawain and the Green Knight" tells of how the courageous Sir Gawain volunteered to fight against the Green Knight in his challenge to King Arthur and his men. The Green Knight had come to the King's court and asked for a challenge.

When the Green Knight had challenged the king and his men, no one seemed to be ready to accept it. For the challenge is quite dangerous, giving three blows to the knight and if he is not dead, receiving three blows. This dangerous bet was finally accepted by the king himself for he did not want to seem like a coward. Then, Sir Gawain volunteered to take the King's place. So, he proceeded to take part in the bet. The lines provided in the question shows that Gawain is ready to fight the Green Knight as he had withstood three blows.
