וְנִסְכֵּיהֶ֗ם חֲצִ֣י הַהִין֩ יִהְיֶ֨ה לַפָּ֜ר וּשְׁלִישִׁ֧ת הַהִ֣ין לָאַ֗יִל וּרְבִיעִ֥ת הַהִ֛ין לַכֶּ֖בֶשׂ יָ֑יִן זֹ֣את עֹלַ֥ת חֹ֙דֶשׁ֙ בְּחָדְשׁ֔וֹ לְחָדְשֵׁ֖י הַשָּׁנָֽה׃
And their drink-offerings shall be half a hin of wine for a bullock, and the third part of a hin for the ram, and the fourth part of a hin for a lamb. This is the burnt-offering of every new moon throughout the months of the year.
Rashi on Numbers
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).
Rabbeinu Bahya
Rav Hirsch on Torah
V. 14. ונסכיהם und diese Hingebung bildet Israels reinste Glückseligkeit und steigt mit jeder höheren Stufe der Bedeutsamkeit, deren es sich vor Gott bewusst werden darf.
