Matthew Poole and continuators on Hebrews 10:28

28 He that despised Moses law, died without mercy, under two or three witnesses.

The Punishment threatned on such Sinners, is illustrated by an Instance proper to the Hebrews; for if the lesser Sin against Moses's Law was punished by Death, the greater Sin against the Gospel of Christ shall be more punished. Any Person whoever he were, none excepted, contemning, rejecting, nullifying, or making to have no place or force (suitable to forsaking before prohibited) the Law of God, given by the Mediation of Moses, so as to have no power on the Conscience by apostacy from it, and to do it openly, proudly and presumptuously in the face of the Church, Num. 15.30, 31.

Was to be sentenced to death, without any Compassion or Mercy, and indispensibly executed without any Pity, by stoning of the Offender by two or three Witnesses, which did evidence the Fact, and convict him of it, according to the Law, as Deut. 13.6, to 22. and 17.2. to 8.
