Albert Barnes Commentary Ezekiel 46:4

"And the burnt-offering that the prince shall offer unto Jehovah shall be on the sabbath day six lambs without blemish and a ram without blemish;" — Ezekiel 46:4 (ASV)

The offerings prescribed here (Ezekiel 46:4–15) are generally in excess of those required by the Law, to indicate not only the greater devotion and magnificence under the new state of things, but also the willingness of king and people ready to give from their resources to the utmost of their means.
