The word "Prime" comes from Latin and refers to the first hour of daylight (that which begins at sunrise). John Cassian (c. 360 – c. 435) describes it as "matutina" ("hora"), ("a" or "the") "morning hour" (translated also as "Mattins"), a description applied also, according to Alardus Gazaeus even by Cassian, to the dawn hour of Lauds. Benedict of Nursia (c. 480 − c. 547) refers to Prime by using the term ""primae tempore"" ("the time of First Hour") for Prime and uses "matutino tempore" ("morning time") to speak of Lauds, reckoning Lauds as the first of the seven daytime offices, which he associates with Psalm 118/119:164, "Seven times a day I praise you for your righteous rules", and which he distinguishes from the one nocturnal office of Night Watch, which he links with Psalm 118/119:62, "At midnight I rise to praise you, because of your righteous rules",
