Exodus 20: 8-11
8 “Remember the Sabbath day, to keep it holy. 9 Six days you shall labor and do all your work, 10 but the seventh day is the Sabbath of the Lord your God. In it you shall do no work: you, nor your son, nor your daughter, nor your male servant, nor your female servant, nor your cattle, nor your stranger who is within your gates. 11 For in six days the Lord made the heavens and the earth, the sea, and all that is in them, and rested the seventh day. Therefore the Lord blessed the Sabbath day and hallowed it.
We have scriptural proof of what you claim was made up by men
Yes, I have. Firstly, when God - the Word - spoke with Moses about rest in the day of Sabbath, among many other things, it had alreaddy passad around two Days and half or 2.500 years (two millenniums and a half). So, God - the Word - was already working there was two Days. Moses, in his pray to the Lord did say: "a thousand years in thy sight are but as yesterday when it is past". Psalms 90:v.4
JESUS - the Greater Light - came in the fourth Day after Adam, and the Lesser Light came also in the fourth Day or around 4.000 years after Adam, and in the same fourth Day JESUS said to the people of Israel: "My Father worketh hitherto, and I work- John 5:v.16-18:
16 And therefore did the Jews persecute Jesus, and sought to slay Him, because He had done these things on the sabbath day.
17 But Jesus answered them, My Father worketh hitherto, and I work.
18 Therefore the Jews sought the more to kill JESUS because He not only had broken the sabbath, but said also that God was His Father, making Himself equal with God.
1. God RESTED on the 7th day (not is still resting)
2. He created heavens and earth in 6 days
So, we are to WORK for 6 days as he worked for 6 days, and rest on the 7th as he rested on the seventh
Oh you are comparing God - the Word - as whether He be equal you.
How long was the day in Moses day?
The answer is: 24 hours day, as it is until today.
The same length as the day in Gen 1..
No, absolutely not. A Day in Genesis 1 is not 24 hours day, but a thousand years as said Moses in his pray to the Lord God: Psalms 90:v.4
If not, God gave moses a tainted example of work and rest which was not true.
You are saying that. It is written: God is not a man, that He should lie, yes, God is not a human who lies or a mortal who changes His mind.
Again, evening and the morning, , You can’t get past that,
What the Most High and Almighty God - the Word - revealed unto Moses in His plan of restoration of all things through JESUS - Genesis 1 - is that He started to work at evening (or afternoon), of the first Day, I would say a period of around 500 years after the fall of man in Eden, and ended His works of the first Day at the morning of the Day after, the second Day.
The material things are figures of spiritual things. God revealed these two distincts periods of work unto Moses, it means 2 periods of 500 years each one, and a complete period of 1,000 years, and so on. Psalms 90:v.4 - For from your viewpoint a thousand years are merely like yesterday or a night watch. So teach us to count our days, so that we will become wise. Psalms 90:v.12
