Why does the Torah repeat "Mo'adei Hashem"?
Rashi: Pasuk 2 is referring to arranging an Ibur Shanah (a leap-year), 1 and the current Pasuk, to Kidush ha'Chodesh - the Mitzvah on Beis-Din to sanctify each month. 2
Ramban: Refer to 23:3:1:3*.
R. Bachye: "Eileh" implies permanence - to teach us that the Yamim-Tovim will last forever, as long the world exists in its physical form. 3 4
See also R. Bachye citing Pirkei de'R. Eliezer, who describes in detail 'Ibur Shanah' - which could only be performed by the Sanhedrin in Eretz Yisrael - though he Gemara in Rosh Hashanah 25a rules that if the Gadol ha'Dor is in Chutz la'Aretz, then he should arrange Ibur Shanah.
See R. Bachye.
R. Bachye: And it is about them that the Pasuk writes in Tehilim 111:8 "Semuchim la'Ad le'Olam Asuyim be'Emes ve'Yashar".
How will we reconcile "Eileh Mo'adei Hashem" with "asher Tikr'u osam (Atem)"?
Yerushalmi Rosh Hashanah, 1:3: 'Until now they were My festivals; from now on they are your festivals!' 1
