Hebrews 10:28 Commentary and Bible Study

The significance of this – and it comes from Numbers 15:31, where Moses announces from God, the most serious punishment of all upon people who despise the law. In those times under the Old Testament, if you showed that you despised the law, rejected it, set it aside, then it was a sentence of death. There were very many offences that did not merit a sentence of death, but to despise the law and say, ‘It is nothing to me. I am not under its moral demands, I put it aside’; that in the ancient theocracy warranted the death sentence. He that despised Moses Law died without mercy.
