וְהָיָ֗ה מִֽדֵּי־חֹ֙דֶשׁ֙ בְּחָדְשׁ֔וֹ וּמִדֵּ֥י שַׁבָּ֖ת בְּשַׁבַּתּ֑וֹ יָב֧וֹא כָל־בָּשָׂ֛ר לְהִשְׁתַּחֲוֺ֥ת לְפָנַ֖י אָמַ֥ר יְהוָֽה׃
Y será que de mes en mes, y de sábado en sábado, vendrá toda carne á adorar delante de mí, dijo SEÑOR.

Rosh Chodesh (the New Moon/Month) symbolizes the future, renewal. The holiness of Rosh Chodesh is not mentioned in the Torah for the Torah is of the holiness that continues out of the past, but Rosh Chodesh deals with the holiness of the future. And this matter of the holiness of Rosh Chodesh which is not mentioned at all in the Torah, for the Shekhinah was not revealed in the past, only in the future, as it says: And it shall come to pass, that every new moon, and every sabbath, shall all flesh come to bow down to the ground before me, says the Lord (Isaiah 66:23). For ultimately in the future there will be singing at all times of the Shir Chadash (the new song), just as God, blessed be He, has no bound or end, thus perception of him will be boundless. And at every moment they will perceive further recognition at new and additional levels without end. Only in this world (Olam HaZeh) which is finite is our perception bounded.
