Midras Keluaran 22:24: Mekhilta DeRabbi Yishmael, Bereshit Rabbati, Ein Yaakov (Glick Edition) & Midrash Tanchuma Buber

(Exodus 22:24) "Im you lend money to My people": R. Yishmael says: Every "im" (generally "if") in the Torah connotes optionality, with the exception of this and two others; (Leviticus 2:14) "And im ("when") you offer a meal-offering of first-fruits," where it is mandatory. You say it is mandatory, but perhaps it is optional? It is, therefore, written (Ibid. 14) "You shall bring the meal-offering of your first-fruits." It is mandatory and not optional.

(Genesis 45:8) "So it was not you who sent me here, but God; and He has made me a father to Pharaoh." I am like a creditor to him, as it is stated (Exodus 22:24), "Do not impose interest upon him." Just as the way of a creditor is to lend to a borrower (Proverbs 22:7), in the book of Rabbi Meir, it is written, "And he has made me a father," as it says, "which the Lord, your God, gives you" (Deuteronomy 15:2). This is a legal judgment derived from the full texts written in the Torah, which emerged from Jerusalem during the Sabbatical year and ascended to Rome, and the scrolls were stored in the synagogue of Asvyros. "And God saw all that He had made, and behold, it was very good" (Genesis 1:31). "For a man and his wife, leather tunics" (Genesis 3:21). "I will descend now and see their outcry" (Genesis 18:21). "The Lord who took me from my father's house and from the land of my birth" (Genesis 24:7). "And he sold his birthright" (Genesis 25:33). "Behold, now, I am old; I do not know the day of my death" (Genesis 27:2). "The fragrance of a field that the Lord has blessed" (Genesis 27:27). "And Oholibamah bore Jeush" (Genesis 36:5). "Eliphaz, the son of Esau" (Genesis 36:10). "These were the sons of Oholibamah, the wife of Esau" (Genesis 36:14). "They arose and went down to Egypt" (Genesis 43:15). "And I buried her there on the way" (Genesis 48:7).And he has made me a father to Pharaoh." And here are the names that came down to Egypt (Genesis 46:8). "So shall you say to the children of Jacob, and tell the children of Israel" (Exodus 19:3). "The children of Israel journeyed from Rameses" (Exodus 12:37). "For it is a sign between Me" (Exodus 31:13). "Five for the planks on one side" (Exodus 26:27). "We have no barricade against it." "And the priest shall take from its blood" (Leviticus 4:34), for if it is a lamb. "And when the zav becomes purified with living water" (Leviticus 15:13). "One lamb of the first year without blemish" (Leviticus 14:10). "All who come to join the ranks must be counted in their census" (Numbers 4:3). "From the first of your dough, you shall give" (Numbers 15:20). "Avenge the vengeance of the children of Israel" (Numbers 31:2). "And they came to Moses and to the congregation of the children of Israel" (Numbers 12:1). "The heads of the families of the house of Joseph approached" (Numbers 36:1). "But I have not the power to go up" (Deuteronomy 1:26). "And they shall inherit it, they and all the people of the land" (Numbers 32:22). "To give us into the hands of the Amorites" (Deuteronomy 1:27). "Nor take a mother upon her young" (Deuteronomy 22:6). "Brimstone and salt burning" (Deuteronomy 29:22). "Like the upheaval of Sodom and Gomorrah" (Deuteronomy 29:22). "I said, I would scatter them" (Deuteronomy 32:26). So they are written in the Torah that emerged from Jerusalem.

Our Rabbis were taught: He who annoys a stranger transgresses three negative commandments, and he who oppresses him transgresses two. Let us see, Regarding annoying, there are three negative commandments, (Ex. 22, 20; Lev. 19, 33 and 25, 17). If so, then there are three negative commandments concerning oppression also (namely, Ex. 22, 20; 23, 9 and 22, 24) — which include also the stranger. We must therefore say that in both cases, he transgresses three negative commandments.
