“Abram took Sarai his wife, and Lot, son of his brother, and all their property that they had acquired, and the people that they had made in Ḥaran; they departed to go to the land of Canaan and they came to the land of Canaan” (Genesis 12:5). “And the people that they had made in Ḥaran” – Rabbi Elazar bar Zimra said: If all the inhabitants of the world were to assemble, to create even a single gnat, they would be unable to inject a soul into it, and yet you say: “The people that they had made?”
The explanation is that this refers to the proselytes that they converted. If so, [it should have said] “that they converted”; why “that they made”? It is to teach you that anyone who draws an idol worshipper near and converts him, it is as though he has created him. Let it, then, say: “that he made”? Rav Huna said: Abraham converted the men and Sarah converted the women.
