Talmud for Rosh Hashanah 35:5

Rebbi Ḥiyya bar Abba was standing praying. Rebbi Cahana came and stood behind him in prayer. When Rebbi Ḥiyya had finished, he sat down in order not to walk by him. [Rav Cahana spent a long time praying.]¹⁰⁰In this paragraph, the corrector’s additions are from Sanhedrin. After he finished, he told him, is that your way to make your superiors suffer? He told him, I am a descendant of the House of Eli, of whom it is written¹⁰¹1S. 3:14. Babli 18a.: if the sin of the House of Eli would forever be atoned for by sacrifice and offering. By sacrifice and offering it cannot be atoned for, [but] it can be atoned for by prayer. He prayed for him, he reached old age while his fingernails remained red like those of a small child.
