Charles Ellicott Commentary Genesis 25:11

"And it came to pass after the death of Abraham, that God blessed Isaac his son. And Isaac dwelt by Beer-lahai-roi." — Genesis 25:11 (ASV)

God blessed his son Isaac. —With this general summary the Tôldôth Terah concludes, and no portion of Holy Scripture is more interesting or valuable; for in it the broad foundation is laid for the fulfilment of the protevangelium contained in Genesis 3:15, the progenitor of the chosen race is selected and proved on trial, and the preparation made for the giving of the Law, and for the growing light of prophecy, by the nearness with which Abraham walked with God.
