John Trapp on Hebrews 10:28

Verſe 28. He that despiſed] i. e. He that with a high hand violated it, or fell into any capitall crime, and it came to light, died without mercy. As for thoſe hainous offences, that not being diſcovered, and ſufficiently proved, came not under the Judges cognizance, the Lord, for the eaſing of mens conſciences, and for the ſaving of their lives, appointed they yearly feaſt of expiations, Levit. 16.29.
