Jeremiah 44:28

Only a few of the Judean remnant living in Egypt would survive (cf. Jeremiah 44:14). The Lord’s people then would know whose word was true. They had said that if they worshipped the Queen of Heaven, they would prosper, but He had said they would perish.

Many Jews continued to live in Egypt for hundreds of years after these events. [Note: See J. P. Lange, ed., A Commentary on the Holy Scriptures, vol. 6: The Book of the Prophet Jeremiah Theologically and Homiletically Expounded, by E. W. Eduard Naegelsback, p. 356, for a brief history of Jewish life in Egypt until the time of Christ.] This may indicate that many of the Jews repented at Jeremiah’s preaching and that God spared them, but this is unlikely. Probably the Lord slew the Jews who had fled to Egypt with Johanan.
