It still doesn't point to being six literal days of creation,.. it just says that the seventh day is the sabbath day. Again, we're not sure what was defined to being a day for God. I can see why one would think that though because of the sabbath thing, but God only knows.
KJV Exodus 23:12
12 Six days thou shalt do thy work, and on the seventh day thou shalt rest: that thine ox and thine ass may rest, and the son of thy handmaid, and the stranger, may be refreshed.
Why would the six days not be literal... God makes them literal in His own Commandments to Israel... He didn't say make them as long as you like.
KJV Exodus 24:16-17
16 And the glory of the LORD abode upon mount Sinai, and the cloud covered it six days: and the seventh day he called unto Moses out of the midst of the cloud.
17 And the sight of the glory of the LORD was like devouring fire on the top of the mount in the eyes of the children of Israel.
KJV Exodus 31:17-18
17 It is a sign between me and the children of Israel for ever: for in six days the LORD made heaven and earth, and on the seventh day he rested, and was refreshed.
18 And he gave unto Moses, when he had made an end of communing with him upon mount Sinai, two tables of testimony, tables of stone, written with the finger of God.
KJV Leviticus 23:3
3 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.
And yes. There is another sense in which Peter declared that metaphorically 1000 years is to the Lord as one day. Which is interesting if you consider the chronology of mankind...6000 years...6 days... With the millennium, the 7000th "day" becoming a rest for the earth being uninhabitable for that entire period... The earth, after 6000 years of having no rest from sin and the labor of man with all the pollutions and abuse, will finally have it's sabbath rest before the creating of the new earth.
