Midrash for II Kings 3:4

R. Nahuniah the son of Hakanah maintained that righteousness exalteth a nation alludes to Israel, while sin is a reproach to any people is applicable to the idolatrous nations that sinned against Israel. From whom do you learn this? You learn it from Mesha, king of Moab, for it is said: Now Mesha king of Moab was a sheep-master (II Kings 3:4). What is meant by a noked (“sheep-master”)? He was shepherd, for it is said: And he rendered unto the king of Israel the wool of a hundred thousand lambs and a hundred thousand rams (ibid.). What is meant by the wool of rams? R. Abba the son of Kahana said: Sheep. What did he do? He assembled all his astrologers and said to them: “I have a problem, tell me what to do. Should I wage war together with all the nations against Israel and exile them, or should I wage war alone against Israel so that the victory might be mine alone?’ They replied: “Israel had a patriarch called Abraham who was given a child when he was one hundred years old, and he offered him as a sacrifice.” He asked them: “Was the sacrifice completed?” “No,” they answered. He replied: “He offered a sacrifice that was not completed and yet He performed miracles for them, how many more miracles would He have performed if the sacrifice had been completed. Now, since I have a firstborn son who will rule in my stead, I shall offer him as a sacrifice, and perhaps a miracle will be performed in my behalf.” Hence it is written: Then he took his eldest son that should have reigned in his stead, and offered him for a burnt-offering upon the wall, and there came a great wrath upon Israel (II Kings 3:27–28).
