This time frame has nothing to do with us, and we are not Israel, and in God's sight today there is no difference in me a Gentile, and one that is from the blood line "Israel" the man.
Can you show me in the era of Exodus, before the "Time of the Gentiles", that Sunday, Monday, Tuesday, etc. was used to identify the days of the week? Scripture shows they counted the days, viz. day 1, day 2, and the only day named was the Sabbath. This is the way they kept the time of the days, from the Sabbath. The next day was the "first day", and then the "second day", until they reached the "6th day". They knew the "7th day", was the Sabbath, and then they again begin to count over. This is done all the way through the Bible. It does not conform to what we may imply in our "worldly knowledge". His Word is not of this world.
