Ambrose of Milan
Some have pondered why Matthew enumerates forty-two generations from Abraham to Christ, whereas Luke records fifty, and why their genealogies trace through different individuals. This reinforces our earlier point: while Matthew highlights certain ancestors of the Lord and Luke emphasizes others, both accounts affirm that their lineage traces back to Abraham and David. One should not be astonished to find more generations listed by Luke than by Matthew, as the genealogies progress through distinct figures. Some individuals live much longer, while others from different lineages may pass away prematurely; we observe that many elderly individuals are blessed to witness their grandchildren, while others depart this life having barely raised their children.
