Genesis 11:13

And after he became the father of Shelah, Arphaxad lived 403 years and had other ¹  sons and daughters. ² 

Ge 11:13

¹ tn The word “other” is not in the Hebrew text, but is supplied for stylistic reasons.

² tc The reading of the MT is followed in vv. 11-12; the LXX reads, “And [= when] Arphaxad had lived thirty-five years, [and] he fathered [= became the father of] Cainan. And after he fathered [= became the father of] Cainan, Arphaxad lived four hundred and thirty years and fathered [= had] [other] sons and daughters, and [then] he died. And [= when] Cainan had lived one hundred and thirty years, [and] he fathered [= became the father of] Sala [= Shelah]. And after he fathered [= became the father of] Sala [= Shelah], Cainan lived three hundred and thirty years and fathered [= had] [other] sons and daughters, and [then] he died.” See also the note on “Shelah” in Gen 10:24; the LXX reading also appears to lie behind Luke 3:35-36.
