Rabbah bar Abuha (orRabbah bar Avuha;Hebrew:רבה בר אבוה) was aBabylonian rabbi of the second generation ofamoraim.

He was a student ofRav,^[1] and resided atNehardea ofBabylonia. He was the teacher and father-in-law ofRav Nachman. After Nehardea had been destroyed by Papa ben Neser in 259, he moved toShekunzib (Hinzebu), and then again moved toShilhe, then toMahuza,^[2] where he settled along with Rav Nachman, and became areligious judge. There are allusions to a number of decisions and rulings made by him while at Mahuza.^[3]

He was related to thehouse of the exilarchs^[4] and is even said to have been an exilarch himself.^[5]Sherira Gaon claimed to be a descendant of his, and of theDavidic line.^[6]

According to legend, Rabbah was a friend of the prophetElijah,^[7] who gave him leaves from paradise, so that he became rich.^[8]

A descendent wasSherira ben Hanina

Rabbah was not a prominent teacher; and he himself admitted that he was not thoroughly versed even in the four orders of theMishnah, which were generally studied in the schools.^[9] Some of his interpretations of various mishnaic passages have been preserved,^[10] as well as confirmations of earlier halakhot^[11] and halakhic decisions of his own.^[12]

• The commandment to love one's neighbor^[13] must be observed even in the execution of a criminal, since he should be granted as easy a death as possible.^[14]
