Talmud - Pesahim 57b פסחים נ״ז ב׳

he signaled contemptuously with his hand and said: If goat is better, let it be sacrificed as the daily offering. The daily offering is a lamb, proving that its meat is preferable to that of a goat. The king said: Since he not only disagrees with me but has no reverence for the monarchy, as evident from his contempt, sever his right hand. He gave a bribe and the official severed his left hand. The king heard that Yissakhar had deceived him and had the official sever his right hand as well. Rav Yosef said: Blessed is God Who took retribution [mitarpesei] from Yissakhar of Kfar Barkai in this world and did not wait to punish him more severely in the next world. His punishment fit the crime; because he would not dirty his hands with sacrificial blood and was overzealous in keeping his hands clean, both his hands were severed.

Rav Ashi said: Yissakhar of Kfar Barkai did not study the Mishna and was an ignoramus who did not know that this halakha is stated explicitly in the mishna. As we learned in a mishna: Rabbi Shimon says: Lambs take precedence over goats in every place they are mentioned in the Bible. I might have thought that this is because it is a more select species. Therefore, the verse states: “If he brings a lamb as his offering” (Leviticus 4:32). The Torah passage where bringing a lamb as a sin-offering is discussed appears after the passage describing the sin-offering of a goat. The inconsistent order teaches that both these animals are equal. Ravina said: Yissakhar did not even read the Bible properly, as it is written: “If a lamb” (Leviticus 4:32), “if a goat” (Leviticus 3:12), teaching: If one wishes let him bring a lamb; if one wishes let him bring a goat. There is no clear preference.

Pesachim 57b recounts Yissakhar of Kfar Barkai's fatal dispute over lambs versus goats and his ignorance of clear halakhic sources on the matter.
