Bahya and the Talmud in [tractate] Sotah write. Why was the stool where the woman sits to give birth called ha-avnaim? This shows us that when the woman is ready to give birth, her feet and other limbs become cold, like a stone. Therefore, the stone is called avnaim. That is, a stone that is cold and so will her body also be cold. Therefore, you should see that when someone’s body becomes cold, then she would certainly give birth. Therefore, you should notice it.30Bahya, Exodus, 1:15–16; B. Sotah, 11b.
