'Shadow' in the Bible

(who serve the representation and shadow of heavenly things, according as Moses was oracularly told when about to make the tabernacle; for See, saith He, that thou make all things according to the pattern which has been shewn to thee in the mountain.)

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.
