Ezekiel 43:18

And he said unto me, son of man, thus saith the Lord God,.... This is the voice of the Lord continued, speaking out of the house to the prophet; see Ezekiel 43:6:

these are the ordinances of the altar: not what go before, concerning the measures of it, but what follow, concerning the sacrifices to be offered on it:

in the day when they shall make it, to offer burnt offerings thereon, and sprinkle blood thereon; this plainly shows that this altar is the altar of burnt offerings; such were to be offered on it, and the blood of them to be sprinkled thereon, as follows; that is, upon the horns, corners, and border of it, Ezekiel 43:20.
