John Gill 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)

And in the day of the new moon it shall be a young bullock without blemish This is also different from the law of Moses, which required two young bullocks and a ram, and seven lambs, (Numbers 28:11) , whereas here only one bullock: and six lambs, and a ram; they shall be without blemish ; and here Kimchi acknowledges again that this is a new thing to be done in future time.

Some have observed, that the seven lambs under the law showed that perfection might be hoped for and expected; but, there being but six now, that this is not yet attained, nor will be till the saints get to heaven; though perfection is come by the priesthood of Christ, whose sacrifice is a perfect and complete one, and by which his people are perfected, and they are complete in him, yet they have no perfection in themselves.
