Six days shall work be done: but the seventh day is the sabbath of rest, an holy convocation; ye shall do no work therein: it is the sabbath of the LORD in all your dwellings. The seventh day is the Sabbath - This, because the first and greatest solemnity, is first mentioned. He who kept not this, in the most religious manner, was not capable of keeping any of the others. The religious observance of the Sabbath stands at the very threshold of all religion. See Clarke's note on Genesis 2:3.
