NET

1 For the law possesses a shadow of the good things to come but not the reality itself, and is therefore completely unable, by the same sacrifices offered continually, year after year, to perfect those who come to worship.

Darby

1 For the law, having a shadow of the coming good things, not the image itself of the things, can never, by the same sacrifices which they offer continually yearly, perfect those who approach.

KJV

1 For the law having a shadow of good things to come, [and] not the very image of the things, can never with those sacrifices which they offered year by year continually make the comers thereunto perfect.
