Midrash su Genesi 24:62

Our sages, however, maintained that she was actually a different wife. Rabbi insisted: Hagar and Keturah were one and the same person, since it is written about Isaac: And Isaac came from the way of Beer-lahai-roi (Gen. 24:62); that is, from the well of which it is written: And she called the name of the Lord that spoke to her, Thou art a God of seeing (ibid. 16:13). From this you learn that she must have been Hagar.⁹A well opened for Hagar after she and Ishmael were sent away (Gen. 21:19). God saw her plight.

What is written before this passage (Gen. 25:1)? (Gen. 24:62:) NOW ISAAC HAD COME BY WAY OF BEER-LAHAI-ROI.³⁶See Tanh., Gen. 5:8; cf. Gen. R. 60:14; 61:4. And afterwards < it is written > (in Gen. 25:1): THEN ABRAHAM TOOK A WIFE AGAIN.³⁷This translation of the verse, which is somewhat more literal than the usual English renderings, suggests how Rabbi could interpret it to mean that Abraham had remarried Hagar. It is simply that when Isaac took Rebekah, Isaac said: Let us go and bring a wife to my father. Hagar and Keturah are the same person < according to > the words of Rabbi, but our masters say he took another wife. What is the logic of Rabbi? Hagar and Keturah are the same person because it is written (in Gen. 24:62): NOW ISAAC HAD COME BY WAY OF BEER-LAHAI-ROI. < Here is a reference to > the same woman about whom it is written (in Gen. 16:14): THEREFORE THE WELL WAS CALLED BEER-LAHAI-ROI.³⁸The context suggests that Beer-lahai-roi might have been where Hagar had settled.

And he dwelt in the land of Midian; and he sat down by a well. In so doing, he repeated what his ancestors had done previously. There were three who met their mates at a well: Isaac, Jacob, and Moses. Isaac, as it is written: And Isaac came from the way of Beer-lahai-roi (Gen. 24:62). Jacob, as it is written: And he looked up, and behold, a well in the field (ibid. 29:2). Moses, as it is written: And he sat down by a well.
