Read Deuteronomy 17:12 Using Other Translations

The man who acts presumptuously by not obeying the priest who stands to minister there before the LORD your God, or the judge, that man shall die. So you shall purge the evil from Israel.
Anyone arrogant enough to reject the verdict of the judge or of the priest who represents the LORD your God must die. In this way you will purge the evil from Israel.
