Rashi (from Bava Basra 16a-b): A Ya'al (wild goat) hates its child. It ascends a mountain ¹ so that the baby will fall to its death when it is born. I prepare an eagle to catch the baby on its wings, and return it to the mother. If the eagle would come a moment earlier or later, the baby would die. I did not miscalculate by a moment. Did I confuse Oyev and Iyov?!

Rashi (from Bava Basra 16b): Cholel is like "Chil ka'Yoledah." The womb of an Ayal (hart) is narrow. When it is ready to give birth, I send a snake to bite it, causing the womb to open more. If the snake would come a moment earlier or later, it would die. I did not miscalculate by a moment. Did I confuse Oyev and Iyov?!
