Matthew Poole and continuators on Ezekiel 43:21

21 Thou shalt take the bullock also of the sin-offering, and he shall burn it in the appointed place of the house without the sanctuary.

As verse 20. let. x.

The Priest of Zadok's line, that by his course in ministration, ought at that time to offer the Sacrifice.

Either the whole, or so much as is commanded to be burnt.

The house here is not the Temple it self, but a place within the circuit of the most Consecrated ground; 'tis called the place of the house, because the place in which the house was built, which is the Sanctuary or Temple. This was done without the Gate, without the Camp, while the Tabernacle stood. Now 'tis to be done in the Court of the house, and on the Altar appointed and consecrated, this is the first days Sacrifice.
