So your point here is what? New moons are for times and seasons *
Genesis 1. Why do you not think there will be times and seasons in the new heavens and the new earth? I think you missed the point though. The Sabbath is not a shadow is why Issiah 66:22-23 was quoted.
It seems that you skimmed right past YHWH's Moedim.
Paul mentions all three in this passage:
(CLV) Col 2:16
Let no one, then, be judging you in food or in drink or in the particulars of a festival, or of a new moon, or of sabbaths,
(CLV) Col 2:17
which are
a shadow of those things which are impending—yet the body is the Christ's.
I agree with Paul; as Paul agrees with the Torah.
(CLV) Hb 3:16
For some who hear embitter Him; but not all those coming out of Egypt through Moses.
(CLV) Hb 3:17
Now with whom is He disgusted forty years? Was it not with those who sin, whose carcasses fall in the wilderness?
(CLV) Hb 3:18
Now to whom does He swear, not to be entering into His stopping, except to the stubborn?
(CLV) Hb 3:19
And we are observing that they could not enter because of unbelief.
(CLV) Hb 4:1
We may be afraid then, lest at some time, a promise being left of entering into His stopping, anyone of you may be seeming to be deficient.
(CLV) Hb 4:2
For we also have been evangelized, even as those also. But the word heard does not benefit those hearers, not having been blended together with faith in those who hear.
(CLV) Hb 4:3
Then we who believe are entering into the stopping, according as He has declared, "As I swear in My indignation, `If they
shall be entering into My stopping!'" although the works occur from the disruption of the world.
Do you believe that this stopping is the seventh day sabbath; or could it be that the seventh day sabbath, is a shadow of the Shabbat to come as we tabernacle with Yahshua, paralleled by the seventh Moed, Sukkot (Feast of Tabernacles.)
And ye shall keep it a feast unto YHWH seven days in the year. It shall be a statute FOREVER in your generations: ye shall celebrate it in the seventh month.(Leviticus 23:41)
(CLV) Zch 14:16
And it will come to be that everyone left of all the nations coming against Jerusalem, they will also go up, as often as year by year, to worship the King, Yahweh of hosts, and to celebrate the festival of booths.
