II Chronicles 31:3 Midrash

וּמְנָת֩ הַמֶּ֨לֶךְ מִן־רְכוּשׁ֜וֹ לָעֹל֗וֹת לְעֹלוֹת֙ הַבֹּ֣קֶר וְהָעֶ֔רֶב וְהָ֣עֹל֔וֹת לַשַּׁבָּת֖וֹת וְלֶחֳדָשִׁ֣ים וְלַמֹּעֲדִ֑ים כַּכָּת֖וּב בְּתוֹרַ֥ת יְהוָֽה׃

He appointed also the king’s portion of his substance for the burnt-offerings, to wit, for the morning and evening burnt-offerings, and the burnt-offerings for the sabbaths, and for the new moons, and for the appointed seasons, as it is written in the Law of the LORD.
