Ambrose of Milan — as excerpted in the Catena Aurea on Luke 3:23-38

“Nor do the Evangelists seem so to differ who have followed the old order, nor can you wonder if from Abraham down to Christ there are more successions according to Luke, fewer according to Matthew, since you must admit the line to have been traced through different persons. But it might be that some men have passed a very long life, but the men of the next generation have died at an early age, since we see how many old men live to see their grandchildren, while others depart as soon as they have sons born to them.”
