The Book of Ezekiel contains words that Ezekiel prophesied between 592 B.C. and 573 B.C. The Jewish people were exiled in Babylonia. Ezekiel told them that God had punished them because they sinned against him. God was using Babylon to punish them. However, Ezekiel assured them that God would restore them. But eventually another nation would defeat the Babylonians. Ezekiel also prophesied about how God will restore Jerusalem and the temple so that the people can worship and sacrifice to him again. Ezekiel then described how the land will be divided among the tribes of Israel.
Several chapters of the Book of Ezekiel give instructions about building a new temple. This temple is not the same as the temple the people would build after going back to Jerusalem. Because Ezekiel's temple has never been built, some scholars think that this temple is to be built in the future. Other scholars think that Ezekiel's temple is symbolic of the Church.
The sacrifices in Ezekiel 46 are somewhat different than the required sacrifices in Numbers 28. This may be because Ezekiel prophesied about a new temple with new sacrifices.
The Book of Ezekiel has many complicated visions. Some are similar to passages in other Scripture books that describe future events. Some of these visions are about God rescuing Israel in the distant future. Translators should avoid trying to explain these visions in their translations. Instead, present the visions as they are in the source text.
This is a common phrase in the Book of Ezekiel and is meant to assure the reader that these messages truly came from God, and that he will do what he has promised.
