3:23-38 This genealogy reverses Matthew’s order (Matt 1:1-17). Luke lists Jesus’ lineage back to Adam, possibly to show Jesus’ connection with all humanity as the Son of God (Luke 3:38). Matthew’s genealogy descends from Abraham to Joseph, highlighting Jesus’ status as the rightful heir of David’s throne and the recipient of God’s promises to Abraham. The great differences between the two genealogies have led some to propose that Luke’s genealogy is that of Mary (see study note on 3:23), who was probably among Luke’s primary sources. 3:23 Jesus was about thirty years old: This is the only reference in the New Testament to Jesus’ age during his public ministry, and it is an approximation. Jesus was born 6~4 BC (see study note on 2:2) and began his ministry AD 27~29 (see study note on 3:1), so Jesus was evidently 31~35 years old when he began his public ministry. • known as the son of Joseph: Jesus was the legal but not the biological son of Joseph. • Joseph was the son of Heli: If this is actually Mary’s genealogy (see study note on 3:23-38), then Joseph was Heli’s son-in-law, a possible understanding of the Greek sentence.
