Under the law the people were ordered to work for six days and to rest on the seventh, [and] to plow and reap for six years and desist during the seventh, because the Lord completed the creation of the world in six days and desisted from his work on the seventh. Mystically speaking, we are counseled by all this that those who in this age (which is comprised of six periods), devote themselves to good works for the Lord’s sake, are in future led by the Lord to a sabbath, that is, to eternal rest.
