Hagar and the Well (Be'er)

"And God opened her eyes and she saw a well of water." The explanation above was that the well was in her eyes only when she saw it, and when God opened her eyes she saw it, and this is consistent with the meaning of another verse (Numbers 20:8)
"and you shall speak to the rock before their eyes" - they didn't see it for the water was spiritual, from the source of God, so sometimes you see it and sometimes you don't, so understand this!

Our sages, however, maintained that she was actually a different wife [to Abraham]. Rabbi Yehudah haNasi reasoned: 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, You are 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.

. וירא והנה באר בשדה, “he looked, and behold here there was a well on a field.” Every single one of our patriarchs had an encounter with a well and in each case the well was an allusion to future happenings. In Yitzchak’s case the well he encountered was called באר מים חיים. (26,19) Bereshit Rabbah 70,8 explains that to the Jewish people Torah is equivalent to spring water.

On the matter of “the song of the well, rise up well and answer her.” Because the opening of the well is dependent on the awakening of

בור the Children of Israel, as it is written: “Drink water from your cistern, and flowing waters from within your באר well.” (Proverbs 5, 15) We have taught that cistern is gathered waters, and the hint is to the ways of nature. Because it is established from creation that everything will act according to nature. But “the flowing waters from within your well” is the opening of the source and the root, the aspect of the wellspring. And this is the aspect of Shabbat. And this is the root of all the blessings, as it is brought in the holy Zohar that manna is not found on Shabbat but all blessings are dependent on it.

The mouth of the well was created on Shabbat evening at twilight as it is written: “Drink water from your cistern, and flowing waters from within your well.” Cistern is gathered waters and well is the flowing fountain. And in every person of Israel there is a point of life, as it is written: “And He blew into his nostrils the breath of life,” (Genesis 2, 7) It is just that a person has to find this point. And this is the work of a person, to draw all of his actions to this point. And this is “drink water from your cistern.” And this is the work of the days of the week. And on the holy Shabbat, 'flowing water from within your well,” because the fountain is opened and new light comes and this is the extra soul.
