Eusebius of Caesarea

(Hist. Eccles. 1.7.) For Matthan and Melchi at different periods had each a son by one and the same wife Jesca. Matthan, who traced through Solomon, first had her, and died leaving one son, Jacob by name. As the Law forbade not a widow, either dismissed from her husband, or after the death of her husband, to be married to another, so Melchi, who traced through Matthan, being of the same tribe but of another race, took this widow to his wife, and begat Heli his son. Thus shall we find Jacob and Heli, though of a different race, yet by the same mother, to have been brethren. One of whom, namely Jacob, after Heli his brother was deceased without issue, married his wife, and begat on her the third, Joseph, by nature indeed and reason his own son; whereupon also it is written, And Jacob begat Joseph. But by the Law, he was the son of Heli; for Jacob, being his brother, raised up seed to him. Thus the genealogy, both as recited by Matthew, and by Luke, stands right and true; Matthew saying, And Jacob begot Joseph; Luke saying, Which was the son, as it was supposed, (for he adds this withal,) of Joseph, which was the son of Heli, which was the son of Melchi. Nor could he have more significantly or properly expressed that way of generation according to the Law, which was made by a certain adoption that had respect to the dead, carefully leaving out the word begetting throughout even to the end.
