This episode looks at Luke 3:24, “the son of Matthat, the son of Levi, the son of Melchi, the son of Jannai, the son of Joseph.” Why does Joseph have a different father according to Luke and Matthew? One reason could be levirate marriage (cf. Deut. 25:5). If so, God takes methodical care to preserve the Davidic line for the coming of Jesus, and in that we can both rejoice and trust.
