(9) Sarah saw the son whom Hagar the Egyptian had borne to Abraham playing. (10) She said to Abraham, “Cast out that slave-woman and her son, for the son of that slave shall not share in the inheritance with my son Isaac.” (11) The matter distressed Abraham greatly, for it concerned a son of his. (12) But God said to Abraham, “Do not be distressed over the boy or your slave; whatever Sarah tells you, do as she says, for it is through Isaac that offspring shall be continued for you. (13) As for the son of the slave-woman, I will make a nation of him, too, for he is your seed.” (14) Early next morning Abraham took some bread and a skin of water, and gave them to Hagar. He placed them over her shoulder, together with the child, and sent her away. And she wandered about in the wilderness of Beer-sheba. (15) When the water was gone from the skin, she left the child under one of the bushes, (16) and went and sat down at a distance, a bowshot away; for she thought, “Let me not look on as the child dies.” And sitting thus afar, she burst into tears. (17) God heard the cry of the boy, and an angel of God called to Hagar from heaven and said to her, “What troubles you, Hagar? Fear not, for God has heeded the cry of the boy where he is. (18) Come, lift up the boy and hold him by the hand, for I will make a great nation of him.” (19) Then God opened her eyes and she saw a well of water. She went and filled the skin with water, and let the boy drink.

ויפקח אלהים את עיניה נתן בה דעת להכיר מקום מים שהיה שם כי לא היתה סומא קודם לכן:
ויפקח אלוקים את עיניה, He granted her the instinct to look for water in the place where she would find it. She had not been blind previously so that her eyes had to be “opened.”

Was the well placed there in that moment by divine fiat? Our Rabbis suggest it had been there along, but in Hagar’s grief, she was unable to see it. Strengthened by the angel’s presence and promise, she finds the will to see. This angel is a quiet, lifesaving force giving hope and strength to the anguished in her darkest moments.
(י) וַיִּשְׁלַ֤ח אַבְרָהָם֙ אֶת־יָד֔וֹ וַיִּקַּ֖ח אֶת־הַֽמַּאֲכֶ֑לֶת לִשְׁחֹ֖ט אֶת־בְּנֽוֹ׃ (יא) וַיִּקְרָ֨א אֵלָ֜יו מַלְאַ֤ךְ יְהֹוָה֙ מִן־הַשָּׁמַ֔יִם וַיֹּ֖אמֶר אַבְרָהָ֣ם ׀ אַבְרָהָ֑ם וַיֹּ֖אמֶר הִנֵּֽנִי׃ (יב) וַיֹּ֗אמֶר אַל־תִּשְׁלַ֤ח יָֽדְךָ֙ אֶל־הַנַּ֔עַר וְאַל־תַּ֥עַשׂ ל֖וֹ מְא֑וּמָה כִּ֣י ׀ עַתָּ֣ה יָדַ֗עְתִּי כִּֽי־יְרֵ֤א אֱלֹהִים֙ אַ֔תָּה וְלֹ֥א חָשַׂ֛כְתָּ אֶת־בִּנְךָ֥ אֶת־יְחִידְךָ֖ מִמֶּֽנִּי׃ (יג) וַיִּשָּׂ֨א אַבְרָהָ֜ם אֶת־עֵינָ֗יו וַיַּרְא֙ וְהִנֵּה־אַ֔יִל אַחַ֕ר נֶאֱחַ֥ז בַּסְּבַ֖ךְ בְּקַרְנָ֑יו וַיֵּ֤לֶךְ אַבְרָהָם֙ וַיִּקַּ֣ח אֶת־הָאַ֔יִל וַיַּעֲלֵ֥הוּ לְעֹלָ֖ה תַּ֥חַת בְּנֽוֹ׃ (יד) וַיִּקְרָ֧א אַבְרָהָ֛ם שֵֽׁם־הַמָּק֥וֹם הַה֖וּא יְהֹוָ֣ה ׀ יִרְאֶ֑ה אֲשֶׁר֙ יֵאָמֵ֣ר הַיּ֔וֹם בְּהַ֥ר יְהֹוָ֖ה יֵרָאֶֽה׃
(10) And Abraham picked up the knife to slay his son. (11) Then an angel of the LORD called to him from heaven: “Abraham! Abraham!” And he answered, “Here I am.” (12) And he said, “Do not raise your hand against the boy, or do anything to him. For now I know that you fear God, since you have not withheld your son, your favored one, from Me.” (13) When Abraham looked up, his eye fell upon a ram, caught in the thicket by its horns. So Abraham went and took the ram and offered it up as a burnt offering in place of his son. (14) And Abraham named that site Adonai-yireh, whence the present saying, “On the mount of the LORD there is vision.”

(ז) וַיִּקְרָא אֵלָיו מַלְאַךְ ה' מִן הַשָּׁמַיִם וַיֹּאמֶר אַבְרָהָם אַבְרָהָם (בראשית כב, יא), תָּנֵי רַבִּי חִיָּא לְשׁוֹן חִבָּה לְשׁוֹן זֵרוּז.
(7) "And the angel of Ad-nai called to him out of heaven, and said: Abraham, Abraham" (Gen. 22:11). Rabbi Hiya taught: This is an expression of love, this is an expression of urging.

This angel, then-- comes to a person in his most desperate hour, lovingly holding him to a higher standard even than he has set for himself. Abraham looks up and sees a ram, caught in the thicket, and it occurs to him that he can offer the ram to God as an offering in place of his son. It is an incredible act of hutzpah, to give God a ram when God asks for a child. And yet, the angel’s love has awakened Abraham’s imagination. Before, he thought there was no other way. Now, he suddenly sees what’s possible.
Rabbi Sharon Brous, The Angels Among Us
There are those blessed souls who are tasked in this world with the holy work of transmitting sacred messages. Of planting the seed of hope and possibility in the darkest moments, like Hagar’s angel. Of lovingly holding up a mirror and awakening us to the need to do better, to live in greater alignment with our values, to cherish the preciousness of life, like Abraham’s angel. There are those tasked with wrestling with us, giving us strength and clarity, perseverance and resilience, especially when we’re most vulnerable. There are those whose sacred task it is to gently, subtly point us in the right direction, so that our stories can unfold with grace. There are God’s angels everywhere, who are tasked, as the Book of Psalms promises to protect you wherever you go (Psalms 91:11).
(ב) כָּל הַנִּכְנָסִין לְהַר הַבַּיִת נִכְנָסִין דֶּרֶךְ יָמִין וּמַקִּיפִין וְיוֹצְאִין דֶּרֶךְ שְׂמֹאל, חוּץ מִמִּי שֶׁאֵרְעוֹ דָבָר, שֶׁהוּא מַקִּיף לִשְׂמֹאל. מַה לְּךָ מַקִּיף לִשְׂמֹאל, שֶׁאֲנִי אָבֵל, הַשּׁוֹכֵן בַּבַּיִת הַזֶּה יְנַחֲמֶךָּ.
(2) All who entered the Temple Mount entered by the right and went round [to the right] and went out by the left, save for one to whom something had happened, who entered and went round to the left. [He was asked]: “Why do you go round to the left?” [If he answered] “Because I am a mourner,” [they said to him], “May He who dwells in this house comfort you.”

...the question we’re called to ask one another: (ma lakh)… that’s precisely the question the angel asked Hagar that day she was found weeping and wailing in the desert sun. Ma lakh Hagar—tell me about your pain, Hagar. The message is clear: now it is we—each of us—called to step into the role of angel and ask: (ma lakh)? And in so doing, we become the malakh, the angel, ourselves.
