A more thorough explanation:

Definition: A statement made by a judge or lawyer to the jury about the value of certain evidence presented in a trial.

For example, during closing arguments, a lawyer may comment on the evidence presented in the trial to persuade the jury to see their client's side of the case. A judge may also comment on the evidence in federal court, but in most state courts, judges are not allowed to do so when examining a witness or instructing the jury.

Commenting on the evidence helps the jury understand the significance of the evidence presented and how it relates to the case. It can also help the jury make a more informed decision when reaching a verdict.
