What does Luke 3:32 mean?
When Luke listed Jesus' earthly genealogy (Luke 3:23), one purpose was to show that Jesus fulfilled prophecy as a descendant of David. That was accomplished in the prior verse (Luke 3:31). Luke continues to emphasize that Jesus is also a son of Adam—a human being—whose role as Messiah is available to all people and nations.Names given up to now have mostly been obscure, at best being unknown men named for more famous Old Testament figures. After referencing David, many of the listed men are well-established in Scripture. This verse lists David's father, Jesse (1 Samuel 16:1), his grandfather Obed (Ruth 4:17), and his great-grandfather, Boaz (Ruth 4:13).
The book of Ruth (Ruth 4:18–22) includes the same genealogy as given in these two verses of Luke (Luke 3:33). Sala, in this case, is a slightly different rendering of the name Salmon.
