John Gill Commentary Genesis 24:62

"And Isaac came from the way of Beer-lahai-roi. For he dwelt in the land of the South." — Genesis 24:62 (ASV)

And Isaac came from the way of the well Lahairoi The well at which the angel met with Hagar, when she fled from her mistress, (Genesis 16:7Genesis 16:14) . The Targums of Jonathan and Jerusalem say, that Isaac came from the school of Shem the great:

for he dwelt in the south country : at Beersheba, to which Abraham, it seems, was returned again; for that they dwelt together as yet, is clear from his mother Sarah's tent, into which he introduced Rebekah, (Genesis 24:67) ; see (Genesis 22:19) .
