Charles Ellicott Commentary Ezekiel 46:6

"And on the day of the new moon it shall be a young bullock without blemish, and six lambs, and a ram; they shall be without blemish:" — Ezekiel 46:6 (ASV)

A young bullock ... and six lambs, and a ram. —The law required for the new moons, for a burnt offering, two young bulls, seven lambs, and a ram (Numbers 28:11), so that this sacrifice is diminished here; it also required a he-goat for a sin offering, which is not mentioned here.
