John Wesley on Matthew 5:21

Ye have heard - From the scribes reciting the law; Thou shalt do no murder - And they interpreted this, as all the other commandments, barely of the outward act. The judgement - The Jews had in every city a court of twenty - three men, who could sentence a criminal to be strangled. But the sanhedrim only (the great council which sat at Jerusalem, consisting of seventy - two men,) could sentence to the more terrible death of stoning. That was called the judgment, this the council. Exod 20:13.
