Luke 3:23

GENEALOGY OF JESUS. (Luke 3:23-38) he began to be about thirty--that is, "was about entering on His thirtieth year." So our translators have taken the word (and so CALVIN, BEZA, BLOOMFIELD, WEBSTER and WILKINSON, &c.): but "was about thirty years of age when He began [His ministry]," makes better Greek, and is probably the true sense [BENGEL, OLSHAUSEN, DE WETTE, MEYER, ALFORD, &c.]. At this age the priests entered on their office (Num 4:3). being, as was supposed, the son of Joseph, &c.--Have we in this genealogy, as well as in Matthew's, the line of Joseph? or is this the line of Mary?--a point on which there has been great difference of opinion and much acute discussion. Those who take the former opinion contend that it is the natural sense of this verse, and that no other would have been thought of but for its supposed improbability and the uncertainty which it seems to throw over our Lord's real descent. But it is liable to another difficulty; namely, that in this case Matthew makes Jacob, while Luke makes "Heli," to be Joseph's father; and though the same man had often more than one name, we ought not to resort to that supposition, in such a case as this, without necessity. And then, though the descent of Mary from David would be liable to no real doubt, even though we had no table of her line preserved to us (see, for example, Luke 1:2-32, and see on Luk 2:5), still it does seem unlikely--we say not incredible--that two genealogies of our Lord should be preserved to us, neither of which gives his real descent. Those who take the latter opinion, that we have here the line of Mary, as in Matthew that of Joseph--here His real, there His reputed line--explain the statement about Joseph, that he was "the son of Hell," to mean that he was his son-in-law, as the husband…

Nothing is related concerning our Lord Jesus from his twelfth year to his entrance on his thirtieth year. We often think it would have been a pleasure and advantage to us if we had journals, or at least annuls, of occurrences concerning him; but we have as much as Infinite Wisdom thought fit to communicate to us, and, if we improve not that, neither should we have improved more if we had had it. The great intention of the evangelists was to give us an account of the gospel of Christ, which we are to believe, and by which we hope for salvation: now that began in the ministry and baptism of John, and therefore they hasten to give us an account of that. We could wish, perhaps, that Luke had wholly passed by what was related by Matthew and Mark, and had written only what was new, as he has done in his two first chapters. But it was the will of the Spirit that some things should be established out of the mouth, not only of two, but of three witnesses; and we must not reckon it a needless repetition, nor shall we do so if we renew out meditations upon these things, with suitable affections. In this chapter we have, I. The beginning of John's baptism, and the scope and intention of it (Luk 3:1-6). His exhortation to the multitude (Luk 3:7-9), and the particular instructions he gave to those who desired to be told their duty (Luk 3:10-14). II. The notice he gave them of the approach of the Messiah (Luk 3:15-18), to which is added (though it happened after what follows) the mention of his imprisonment (Luk 3:19-20). III. Christ coming to be baptized of John, and his entrance therein upon the execution of his prophetical office (Luk 3:21, Luk 3:22). IV. His pedigree and genealogy recorded up to Adam (v. 23-38).

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.
