Genesis 25:20

25:20 When Isaac was forty years old, he married Rebekah, ¹  the daughter of Bethuel the Aramean from Paddan Aram and sister of Laban the Aramean. ² 

Genesis 50:3

50:3 They took forty days, for that is the full time needed for embalming. ³  The Egyptians mourned ⁴  for him seventy days. ⁵ 

¹ tn Heb “And Isaac was the son of forty years when he took Rebekah.”

² sn Some valuable information is provided here. We learn here that Isaac married thirty-five years before Abraham died, that Rebekah was barren for twenty years, and that Abraham would have lived to see Jacob and Esau begin to grow up. The death of Abraham was recorded in the first part of the chapter as a “tidying up” of one generation before beginning the account of the next.

³ tn Heb “and forty days were fulfilled for him, for thus are fulfilled the days of embalming.”

⁴ tn Heb “wept.”

⁵ sn Seventy days. This probably refers to a time of national mourning.
