CLAIM: Israel’s end-time salvation and restoration that began in Jeremiah 30 are described. Of particular importance is God’s reference to the restoration after the chastisement of “Ephraim”. This speaks of the ten northern tribes that had been lost and separated from Israel for over 100 years by the time of Jeremiah’s ministry. God will save the remnant of Israel, have mercy on the tribes that were scattered, and bring great blessing and prosperity to all of Israel when her people are re-unified. This happens when all Israel receives the “new covenant” (vv. 31-34) that was established through the death and resurrection of Jesus.
False.
First of all, there were not ten lost tribes. After the division of the Kingdom, the “nation of Judah” refers to the tribes of Judah and Benjamin, and the “nation of Israel” refers to the ten other tribes. They were never lost, and any time those are mentioned, it refers to those tribes. In the second temple period, they were no longer separated, and all 12 tribes (12 + 1, since Ephraim and Manasseh were were both split from Joseph and Levi was not numbered in the tribes since they had the priesthood).
Second, the references to the New Covenant are indeed through the broken body and blood of Jesus at his crucifixion, but the passage speaks only of “will make” the covenant, in which all Christians, Jew and Gentile, now live. It speaks nothing of Israel being welcomed into that covenant in this passage. This will happen in Ezekiel 39 when they believe, and hence, receive the Spirit.
