Commentary on Numbers 28:13

• Matthew Henry (Presbyterian), Matthew Henry's Complete Commentary on Numbers 28:9-15: The new moons and the sabbaths are often spoken of together, as great solemnities in the Jewish church, very comfortable to the saints then, and typical of gospel grace. Now we have here the sacrifices appointed, 1. For the sabbaths.
• Keil & Delitzsch (Lutheran), Biblical Commentary on the Old Testament on Numbers 28:11-15: Num 28:11-15 At the beginnings of the month, i.e., at the new moons, a larger burnt-offering was to be added to the daily or continual burnt-offering, consisting of two bullocks (young oxen), one ram, and seven yearling lambs, with the corresponding meat and drink-offerings, as the “month’s burnt-offering in its (i.e., every) month with regard to the months of the year,” i.e., corresponding to them.
