“ One must mention the exodus from Egypt at night. Rabbi Elazar ben Azaryah said: "Behold, I am like a seventy-year-old man, yet I could not win [the argument against the other sages] having the exodus from Egypt recited at night, until Ben Zoma derived it [from a Biblical source] ." " [He derived it as follows:] It says (Deut. 16:3) , 'In order that you may remember the day when you left Egypt for all the days of your life.'" "Now, 'days of your life' means the days; 'All the days of your life' [includes also] the nights." But the Sages say: "Days of your life" means the present world ”

“ Like a seventy-year-old man: At one point the Sages voted to temporarily demote the nassi (president of the Sanhedrin) , Rabban Gamliel, from his position. (The details of the story are given in the Gemara, Berakhot 27b–28a.) ”
