וְהָיָ֗ה מִֽדֵּי־חֹ֙דֶשׁ֙ בְּחָדְשׁ֔וֹ וּמִדֵּ֥י שַׁבָּ֖ת בְּשַׁבַּתּ֑וֹ יָב֧וֹא כָל־בָּשָׂ֛ר לְהִשְׁתַּחֲוֺ֥ת לְפָנַ֖י אָמַ֥ר יְהוָֽה׃
「每逢月朔，每逢安息日，凡有血氣的都必來到我面前下拜。」這是永恆者說的。

And he who makes his heart as nothing but flesh — his prayer will be heard, as it is written: "All flesh will come to bow before Me, said the Lord" (Is. 66:23) (See Sotah 5a). And it is written: "O Thou that hearest prayer, unto Thee does all flesh come" (Ps. 65:3).
