Jesus himself, when he began to teach, was about thirty years old, being the son (as was supposed) of Joseph, the son of Heli,
The two sons-in-law who are to be noticed in this genealogy are Joseph the son-in-law of Heli, whose own father was Jacob, Matthew 1:16 and Salathiel, the son-in-law of Neri, whose own father was Jechonias: 1 Chronicles 3:17, and Matthew 1:12. This remark alone is sufficient to remove every difficulty. Thus it appears that Joseph, son of Jacob, according to St. Matthew, was son-in-law of Heli, according to St. Luke. And Salathiel, son of Jechonias, according to the former, was son-in-law of Neri, according to the latter.
