The curse on Jeconiah

“This is what the Lord says: ‘Record this man as if childless, a man who will not prosper in his lifetime, for none of his offspring will prosper, none will sit on the throne of David or rule anymore in Judah.’” Jeremiah 22:30
Here we find a very interesting verse. It concerns Jeconiah (also called Jehoiachin, and Coniah), a king who ruled over Judah at the time when Nebuchadnezzar was making Judah a vassal state of Babylon. God pronounces a curse on Jeconiah and all his descendants, that none of them would sit on David’s throne. But before this, God had promised that Messiah would be of the royal line and sit on David’s throne forever (2 Chr. 6:16, Ps. 132:11, Isa. 9:7). So how can God curse the Messiah?
In Matthew 1, we read Jesus’ genealogy, beginning with Abraham, through David, Solomon, all the kings including Jeconiah, down to “Jacob the father of Joseph, the husband of Mary, of whom was born Jesus, who is called Christ” (Matt. 1:16). This wording appears to be carefully chosen. Joseph was not the father of Jesus by blood. There is a second genealogy given to us in Luke 3: beginning with Jesus, saying, “He was the son, so it was thought, of Joseph, the son of Heli” (Luke 3:24). The Greek actually says that Joseph was the son-in-law of Heli. So Heli is Mary’s father, and in Luke 3 we have Mary’s bloodline up to David, then to Abraham, then to Adam.
The curse on Jeconiah was on the blood of the royal line from that point onward. Jesus was the legal son of Joseph, but not the blood son. Yet He was a descendant of David by blood, from His mother’s side. Now it becomes clear what the reference to “the seed of the woman” (Gen. 3:15) means. It also demonstrates that the virgin birth of Christ was absolutely necessary.
