Albert Barnes Commentary Ezekiel 46:13

"And thou shalt prepare a lamb a year old without blemish for a burnt-offering unto Jehovah daily: morning by morning shalt thou prepare it." — Ezekiel 46:13 (ASV)

Compare with marginal references. The evening sacrifice is here omitted, because the seer is selecting a few only of the sacrifices of the Law, with a particular object in view.
