in secundo autem semel in anno solus pontifex non sine sanguine quem offert pro sua et populi ignoranti
but into the second went the high priest alone once every year, not without blood, which he offered for himself, and for the errors of the people:

eritque hoc vobis legitimum sempiternum ut oretis pro filiis israhel et pro cunctis peccatis eorum semel in anno fecit igitur sicut praeceperat dominus mos
and this shall be an everlasting statute unto you, to make an atonement for the children of israel for all their sins once a year. and he did as the lord commanded moses.

porro hoc ad utilitatem vestram dico non ut laqueum vobis iniciam sed ad id quod honestum est et quod facultatem praebeat sine inpedimento dominum observand
and this i speak for your own profit; not that i may cast a snare upon you, but for that which is comely, and that ye may attend upon the lord without distraction.
