A paragraph break is appropriate here since there is a change in speakers (so Revised Standard Version, Good News Bible).

While she was still speaking, the young man said, “What are you waiting for?: The pronoun she may be identified as “the mother.” For the Greek word rendered young man (Good News Bible “boy”), see the introduction to this section. The pronoun you is plural in Greek. In this verse the boy is talking to the executioners. Good News Bible (also Contemporary English Version) has it wrong in having him speak to King Antiochus, but since the boy does speak to the king in the next verse, perhaps Good News Bible thought the difference is not worth preserving. We think it is. New English Bible, Revised English Bible, and New Jerusalem Bible say “you all,” which establishes that the pronoun is plural. It is possible to build in the plural by referring to the executioners not in the boy’s words but in the quote frame as follows: “While she was still speaking, the boy said to the executioners [or, torturers], ‘What are you waiting for? [or, Why wait?]’”

I will not obey the king’s command may be rendered simply “I will not obey the king.”

But I obey the command of the law that was given to our fathers through Moses: The boy defiantly says that he will obey no command that is against the Law of Moses. Here is an alternative rendering: “I do not obey any command that is against the Law that Moses gave our ancestors.”
