SEV Biblia, Chapter 2:3
Los hijos de Judá: Er, Onán, y Sela. Estos tres le nacieron de la hija de Súa, cananea. Y Er, primogénito de Judá, fue malo delante del SEÑOR; y lo mató.
John Gill's Bible Commentary
Ver. 3. The sons of Judah , etc.] The genealogy begins with him, though the fourth son of Jacob; because, as Kimchi says, this book treats chiefly of the kings of Judah; but rather not only because Jesse and David sprang from him, but also the King Messiah: Er, and Onan, and Shelah, which three were born unto him of the daughter of Shua the Canaanitess ; (see Genesis 38:2,12), and Er, the firstborn of Judah, was evil in the sight of the Lord ; because he did that which was evil: and he slew him ; he died by the immediate hand of God, and so his brother Onan, being wicked also, ( Genesis 38:7,10). Ver. 4 . And Tamar his daughter in law bare him Pharez and Zerah , etc.] Through incest; they were twins, ( Genesis 38:27-30) all the sons of Judah were five; who are before mentioned by name.
Matthew Henry Commentary
Genealogies. --We are now come to the register of the children of Israel, tha distinguished people, who were to dwell alone, and not be reckone among the nations. But now, in Christ, all are welcome to his salvatio who come to him; all have equal privileges according to their faith in him, their love and devotedness to him. All that is truly valuabl consists in the favour, peace, and image of God, and a life spent to his glory, in promoting the welfare of our fellow-creatures __________________________________________________________________
