It Is Fitting for the One to Save the Only One

Yalkut Shimoni on Torah 77:1

"I am the LORD who brought you out of Ur of the Chaldees" (Genesis 15:7). They said: At the hour when Nimrod the wicked cast Abraham into the fiery furnace, Gabriel said before Him: Master of the Universe, let me go down and save the righteous one from the fiery furnace. He said to him: I am unique (yachid) in My world, and he is unique in his world; it is fitting for the Unique One to save the unique one. And because the Holy One, blessed be He, does not withhold the reward of any creature, He said to him: You shall merit to save three of his descendants.
