Genesis 25:11

And it came to pass, after the death of Abraham, that God blessed his son Isaac ,.... Yet more and more, both with spiritual and temporal blessings; showing hereby, that, though Abraham was dead, he was not unmindful of his covenant, which should be established with Isaac, Genesis 17:19 ,

and Isaac dwelt by the well Lahairoi ; which was near the wilderness of Beersheba and Paran, where Ishmael dwelt; so that they were not far from one another, see Genesis 16:14 .
