Both lineages are from David but Joseph’s was disqualified because one of his ancestors was cursed.
Disqualified doesn’t change the DNA so they might be cousins or something generations removed(?)
That wouldn’t be perchance be Jeconiah, would it? 😁 I saw a Bible teacher discuss the curse, and how Satan must have thought he had God over a barrel, because of the curse. Then he said he could imagine God telling His angels, “watch this.” Maybe Satan did not anticipate Mary and the virgin birth.
For him, it’s always “dust in the mouth.” The lake of fire, will be the ultimate “dust in the mouth.” 👍
