Daniel, however, fixed the number of prayers that should be recited, as it is said: <i>And he kneeled upon his knees three times a day and prayed</i> (Dan. 6:11).

When Moses realized that Divine justice demanded the extinction of Israel, he cried out: <i>Remember Abraham, Isaac, and Israel</i>, who instituted the three prayers.
