The students of Shammai debated with the students of Hillel for three years, until a Divine Voice announced that although the words of both are the words of the Living Gd, the law follows the students of Hillel, due to their gentle humility: Eruvin 13b R' Pereida had a student who needed to have a lesson repeated 400 times in order for him to learn it properly. Once, the student still didn't understand, and the student explained it was because he had heard someone telling R' Pereida he would have to get R' Pereida for a Mitzvah later, so that the student had his mind on R' Pereida having to leave. R' Pereida then sat and taught him the lesson 400 more times. A Divine Voice emerged and offered R' Pereida 400 years of extra life, or merit for the next world for his generation. R' Pereida took the latter, and so Gd gave him both: Eruvin 54b
