1. Why Did the Angels Need to Tell Sarah?
The question arises: why was it necessary for the angels to inform Sarah that she would have a child? If Hashem—God wanted to give her a baby, He could simply do so without any announcement. The other missions of the angels were practical and required their intervention: overturning Sedom, saving Lot, and healing Avraham after his bris milah—circumcision. But why did an angel need to come specifically to tell Sarah about the forthcoming birth? Does Hashem need to announce miracles in advance?
Furthermore, why didn’t the angels come to tell Avraham? The answer is that Avraham already knew. In last week’s parsha, when Hashem commanded him regarding circumcision, He told Avraham that Sarah would have a son. This was not only once; Hashem had told him twice—once at the bris bein habesarim—covenant between the parts, and again at the end of Parshat Lech Lecha. So Avraham was already aware of the promise.
2. Why Didn’t Avraham Tell Sarah?
The next logical question is: if Avraham knew, why didn’t he tell Sarah? One suggestion is that he thought she wouldn’t believe him. Given her advanced age and physical condition, it seemed impossible for her to have a child. Therefore, Avraham may have reasoned there was no point in telling her something she would find unbelievable.
This leads to another question: if a stranger or even an angel (whom she didn’t recognize as such) came and told her she’d have a child, why would she believe them any more than she’d believe Avraham? The answer is that perhaps Avraham thought when Sarah actually became pregnant, then she would know for herself—there was no need to tell her beforehand.
3. How Did Sarah Hear the News?
The Torah describes that one of the angels spoke to Avraham about the upcoming birth while Sarah was listening from the entrance of the tent. The verse emphasizes that “the entrance was behind him,” meaning behind the angel who was speaking. This detail suggests that the angel did not realize Sarah was listening in.
This raises another issue: if Hashem sent an angel specifically to inform Sarah, why did it happen in such an indirect way? The angel spoke to Avraham, seemingly unaware of Sarah’s presence. It appears from the simple reading of the verse that even angels don’t always know every detail unless Hashem reveals it to them.
4. The Purpose of Indirect Communication
The indirectness here is intentional and meaningful. Hashem wanted Sarah herself to hear and internalize this message—not through direct prophecy or explicit revelation, but by overhearing what seemed like a conversation between guests and her husband. This setup created a test for Sarah: would she believe in something so far beyond nature?
The lesson is profound for us as well: we rarely receive direct messages from Hashem, let alone from angels. Instead, we are meant to pay attention to subtle hints and changes in our lives as possible messages from above.
5. Emunah as a Prerequisite for Miracles
The deeper reason for informing Sarah was that her own emunah—faith and bitachon—trust in Hashem, were necessary prerequisites for her merit (zichus) to bear a child. It wasn’t enough for Avraham alone to believe; Sarah herself needed some level of belief in order for the miracle to occur.
This is why Hashem orchestrated events so that Sarah would overhear this promise and be challenged with believing it despite all natural evidence to the contrary.
6. Nature Versus Faith: The Test of Belief
Sara’s reaction shows how deeply entrenched natural thinking can be. Even after experiencing physical changes indicating youthfulness (as Rashi explains on “Akharei belosi hoisa li edna—after I have withered shall I again be youthful?”), she still found it hard to accept such an unnatural event could happen.
This tension between science/nature and Torah is ongoing: when our minds are conditioned by what seems possible according to nature or science, it becomes difficult to accept miracles or divine intervention as real possibilities.
7. Hashem’s Intervention and Its Message
Sara laughed upon hearing the news because it seemed impossible given her circumstances. At this point, Hashem, not just an angel, intervenes by addressing Avraham: “Why did Sara laugh?” Rashi explains this laughter indicated disbelief, which contrasted with Avraham’s earlier reaction of joy and faith.
This divine intervention wasn’t simply about rebuking Sara but rather about prompting Avraham to encourage Sara’s faith further. Even though Sara was considered a greater prophetess than Avraham on some levels, in this context Hashem's communication came through Avraham so he could strengthen Sara’s emunah.
8. Sara’s Denial and Its Deeper Meaning
The Torah says Sara denied laughing because she was afraid (ki yarei’ah). On a simple level, this seems like denial out of fear or embarrassment. But on a deeper level, Sara wasn’t denying Hashem’s power—rather, she hadn’t realized these words were truly from Hashem since they came through apparent strangers.
Sara’s fear reflects her deep reverence (yiras Hashem)—she would never consciously doubt or mock God’s promise if she recognized it as such.
9. The Enduring Lesson for Us
The story teaches us that we must look at events in our lives as potential messages from above and cultivate trust in Hashem. Even when things seem impossible according to nature or logic, nothing limits God’s ability—a 90-year-old woman and 100-year-old man gave birth to Yitzchak and began our nation’s story.
If we strengthen our emunah and bitachon despite challenges or doubts, we open ourselves up for divine help just as our ancestors did.
