Numbers 28

For because they could not have borne it, if when He was giving the law for the Sabbath, He had said, "Do your good works on the Sabbath, but do not the works which are evil," therefore He restrained them from all alike for, "Ye must do nothing at all," saith He: and not even so were they kept in order. But He Himself, in the very act of giving the law of the Sabbath, did even therein darkly signify that He will have them refrain from the evil works only, by the saying, "Ye must do no work, except what shall be done for your life." And in the temple too all went on, and with more diligence and double toil. Thus even by the very shadow He was secretly opening unto them the truth.
