On another occasion, a disciple officiated in prayer before R. Elazar and was long in his blessings — whereupon they said to him: "This one is an elongater" — to which he countered: "Not more so than Moses, who said (Devarim 9:25) 'And I fell (in prayer) before the L–rd these forty days and forty nights.'" There is a time to be short and a time to be long.
