Numbers 28:14

זאת עלת חדש בחדשו THIS IS THE BURNT OFFERING OF EVERY MONTH IN ITS MONTH — so that if its day is past its offering is cancelled, and there is no supplementary period for it (Sifrei Bamidbar 145:2).

וְנִסְכֵּיהֶ֗ם חֲצִ֣י הַהִין֩ יִהְיֶ֨ה לַפָּ֜ר וּשְׁלִישִׁ֧ת הַהִ֣ין לָאַ֗יִל וּרְבִיעִ֥ת הַהִ֛ין לַכֶּ֖בֶשׂ יָ֑יִן זֹ֣את עֹלַ֥ת חֹ֙דֶשׁ֙ בְּחׇדְשׁ֔וֹ לְחׇדְשֵׁ֖י הַשָּׁנָֽה׃

And their drink offerings shall be half a hin of wine for a bullock, and the third part of a hin for a ram, and a fourth part of a hin for a lamb: this is the burnt offering of every month throughout the months of the year.
