Ezekiel 43:18

18 And he said to me, Thou, son of man, the Lord God saith these things, These be the customs of the altar, in whatever day it is made, that men offer on it burnt sacrifice, and blood be shed out. (And he said to me, Thou, son of man, the Lord God saith these things, These be the customs for the altar, or the way to consecrate it, once it is made, so that people can offer burnt sacrifice on it, and blood can be thrown against it.)

Ezekiel 43:18 Meaning and Commentary

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 ) .

Ezekiel 43:18 In-Context

16 And the altar of twelve cubits in length was four-cornered with even sides, by twelve cubits of breadth. (And the top of the altar was twelve cubits in length, by twelve cubits in breadth, that is, four-cornered with equal sides.)

17 And the height of fourteen cubits of length was by fourteen cubits of breadth, in four corners thereof. And a crown of half a cubit was in the compass thereof, and the bosom thereof was of one cubit by compass; forsooth the degrees thereof were turned to the east. (And so the space for the altar was fourteen cubits in length, by fourteen cubits in breadth, unto its four corners. And a rim of half a cubit was all around it, and its bottom, or its base, was set-in one cubit all around; and its steps were turned toward the east.)

18 And he said to me, Thou, son of man, the Lord God saith these things, These be the customs of the altar, in whatever day it is made, that men offer on it burnt sacrifice, and blood be shed out. (And he said to me, Thou, son of man, the Lord God saith these things, These be the customs for the altar, or the way to consecrate it, once it is made, so that people can offer burnt sacrifice on it, and blood can be thrown against it.)

19 And thou shalt give to priests and deacons that be of the seed of Zadok, that nigh to me, saith the Lord God, that they offer to me a calf of the drove for sin. (Thou shalt give to the levitical priests, who be the descendants of Zadok, and who alone may come near me, saith the Lord God, a calf from the herd, that they offer to me for a sin offering.)

20 And thou shalt take of the blood thereof, and shalt put on four horns thereof, and on four corners of [the] height, and on the crown in compass; and thou shalt cleanse it, and [fully] make clean. (And thou shalt take some of its blood, and shalt put it on the four horns on the top of the altar, and on the four corners of the middle section, and on the the crown all around it; and so thou shalt cleanse it, and make it fully clean.)
