This is the beginning of a new part of the story that runs through [Matthew 25:46](../25/44.md), where Jesus teaches about salvation and the final judgment. Here he begins to warn the people about the scribes and Pharisees.
Here "seat" represents the authority to rule and make judgments. AT: "have authority as Moses had" or "have authority to say what the law of Moses means" (See: [[rc://en/ta/man/translate/figs-metonymy]])
