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 ) ( Genesis 22:17 Genesis 22:18 ) :

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 ) ( Genesis 21:14 Genesis 21:21 ) .
