3. Nedarim 39B - Oaths

R. Joseph thought to explain it: its reward is unlimited.
Said Abaye to him: Is there a definite measure of reward for any precept?
But we learnt: Be as heedful of a light precept as of a serious one, for thou knowest not the grant of reward for precepts?
But Abaye explained it: Even a great person must visit a humble one.
Raba said: [One must visit] even a hundred times a day. R. Abba son of R. Hanina said: He who visits an invalid takes away a sixtieth of his pain. Said they to him: If so, let sixty people visit him and restore him to health?
4. Nedarim 40A
